this sample represents 3,000 years of changing of carbon dioxide. >> the equivalent change of greenhouse that happened in the last decade took thousands of years to happen when the earth was not being influenced by humans. >>> these scientists reflect the fact that 97% of all research published on climate change say it's fuelled by manmade greenhouse gas emissions. >> as scientists we barely agree on anything. to say 97% of climate experts say the climate system is warming today is phenomenal. >>> scientists aside some politicians are not buying it. >> it changes, it gets hot and cold >> but man made? isn't that the question? >> then why did the dinosaurs go extinct? dinosaurs aside, "techknow" went to washington d.c. where a herd of lawmakers don't agree with the scientists we interviewed. like republican senator jeff sessions questioning e.p.a. administrator geena mccarthy. >> would you acknowledge that over the last 18 years, that the increase in temperature has been very little, and that it is well below most of the environmental models that showed how fast temperature would increase

and i think we see real change of emphasis as a result.see the highlighting of the global inequality that has been exacerbating, change in an emphasis on the impact on the poor. that this is not an elite kind of luxury style environmentalism, this is environmental is some of the poor that puts the concerns and the needs of the poor first. amy: this is global. but we are in the mid-of her presidential campaign, and soon we will never be out of presidential campaign season. i want to turn to some of was considered one of the more moderate second republicans, jeb bush. republican presidential candidate jeb bush speaking at a town hall event in new hampshire, he commented on the pope's encyclical. >> i want to read it, but -- first of all, pope francis is extraordinary leader will stop he speaks with such clarity and speak so differently and he is drawn people back into the faith, all of which is a converted catholic now 25 years i think is really cool. i don't get -- i hope i'm not going to get castigated for saying this by my priest back on,

and climate change finishes dead last. in year after year.i think this is going to be a fascinating debate. it will be a heavy lift for those who want to ab vo kate policies are that economically disruptive to those in our society, at the bottom who least afford to pay the expenses that come into play once energy prices as a result of certain policies rise. >> bill, is that the path towards reducing the downside risk for catholic and non-catholic candidates alike. the threat to lifestyle that is posited? >> i'm going to be a sceptic on this one? >> the brookings snaugs where i worked happily has a projected on religion and public policy. we have executed a number of surveys ourselves, and we are struck by the fact that in these partisan, politics, they are driving theo logical presentses more than theology drives political preferences. catholics will find moral and emotional sustenance in the words of the pope, that conservative catholics will find ways of distinguishing what they like about the pope and his message, from what they don't like

recently the national president of the boy scouts told the group the country is changing and the ban on gay leaders should be lifted too. those fighting the change question whether gay men and women can be as the scout oath promises morally straight it will scout's honor is tonight's story. ♪ ♪ ♪ >> welcome to "inside story." i'm ray suarez. boy scouts are central figures in american culture. over the last 100 years you've seen them everywhere, on public service projects in norman rockwell paintings marching in 4th of july parades and marching off to the woods to like and camp. i know because i did it. yeah that's me on the left. i've been involved with scouts in various capacities for most of my life and count the experience as one of the most important and formative in my life. i'm an eagle scout as is my son. like the rest of the organization wrestled with religious beliefs and be sexual orientation. today gay youngsters are allowed to be scouts but gay member and men and women cannot serve as volunteers. just yesterday a call for change came from the top. >> on my honor i will do

we're shifting through we'll prepare a short memo to talk about the changes but there were a few changes and i object to get those to you in the next week. >> commissioners and members of the public we have a fire safety issue here we've got too many people in the room in order to accumulate the people the north court will be televising and you'll be able to watch and lincoln listen and when your item comes up line up outdoor we'll allow for time to people to come back into the room anybody that didn't have a seat go to the light court if you're item is later in the afternoon if you care to giving you give it up a seat the people who's items are coming up next, i appreciate your understanding and cooperation. >> commission on item 5 review of the past events in historic preservation commission meeting. >> good afternoon aaron planning department staff there was no items other full board of supervisors this week the supervisor wiener's ordinance for certain uses in the upper market passed its second reading and the designation for 4th street the manufacturing building passed its second re

soil may change. we have a preview of a special report from miami. >> we're with the j court guard talking about their work and how it's changed since the u.s. flounced plans to normalize with cuba. >> people start talking and migrants take to the sea. >> that's definitely contributed to more migrants. >> we've seen in the wake of the announcement in december an uptick. >> this is the type of cutter you use to go out at sea. >> this i also one of the coast guard's brand new cutters. >> when migrants see you they want to get away, because they don't want to get onboard here to then be sent back to cuba. what's the reaction you get? >> i would say that dependency. when we come across these vessels, they usually are in distress, in need of help and assistance. it's probable and definitely possible they are not going to make it to where they've got to go. >> we've been speaking with recent arrivals and why they've decided to come to the u.s. now. >> the sahara desert is getting bigger and it's happening b

should we change the 15% rural --rule? she we change the 15% role? that is ongoing right now. our subcommittee is the head of the women leave voters and that committee is taking suggestions online. we will look at them, the special committee will, and once we have a chance, we will make recommendations and they will make the decisions. host: when you pick up "the wall street journal" and see this ad two men and their friends is what it looks like, stonewalled and secretive guaranty dominance of the republican parties in presidential elections and saying it is time to change the rule now. your reaction? first of all, what do you think of the picture? guest: we have joked that all that is missing is the numbers on the front of our shirts or jackets. [laughter] guest people have a different : approach to how they want to make change and this is an interesting one. a very expensive one i suggest but again, we have met with those people. i have met with the leader of the change group and so is mike mccurry. they have ported it to every member of the commission, a detailed analysis

>> first of all, issues change and topics change.wants us to be deeply concerned about poor children getting a decent education. the city of baltimore spends $130,000 a year for every student who passes the eighth grade math test. yet there's not a single democrat who's prepared to fundamentally reform the school system. 78% of the country said last week they would be for a candidate who wants major change in the federal government. no democrat is going to run a major change. you would have a madison, wisconsin, uprising on the part of the unions. if the issues next year become who's prepared to reshape the federal government, i think the democrats are in big trouble. if it stays on social ydz issues -- >> you're telling the republican party, no matter what the rural base, don't pander them? >>, no the rural base is deeply opposed to the irs being totally incompetence and the veterans administration unable to serve veterans. preferably if-f you're a conservative, 60% or 70%. that's reagan lesson pu cannot rub with 51% issues and expe

i have three items i would like to make amendments on that are very small changes. so to me, i would rather see if we can i don't know, possibly keep a file on committee, and move forward, follow up with changes if they're able to be supported. so i do think it's important to put something in place for this election. i don't think these issues that are highlighted here, that i'm making amendments on are ones i think should hold up legislation going forward, but i would like to see them incorporated to changes to finance law here in san francisco. i would still be trying to make these amendment, i'm not sure we have the votes at all even here to move amendmentses forward, so let me discuss what those would be. my concerns are what mr. bush has highlighted, i did talk about the first ones, highlighted page four lines 22-23. that is the communication, the exemption for nonprofits, that might be putting on an event, they're not promoting, so much candidacy, but they are putting out a nice photo of the candidate, or mention the candidate's name, ensuring when the candida

was it climate change? according to research published in the bulletin of the meteorological society, probably yes. and what about the winter of 2014, climate change or just wild weather? a study out of oxford university said that that event was probably climate change. california suffered through three years of debilitateing drought. was climate change to blame? probably not. california's drought, while extreme, is not an uncommon occurrence for the state. natural weather trends are the primary factors. still, extremes are becoming the norm. 2014 will go down as the warmest year ever recorded worldwide. for climate scientists understanding why is evolving with every event. california's storm of the decade may, in fact, be tied to a recently observed phenomenon known as atmospheric rivers. >> atmospheric rivers are here to stay. it's chalk full of water vapors, strong winds, and is carrying ten times the water. >> it seems to be very severe weather phenomenon. >> well, there is a lot to learn in terms of at

that is a very important change.er has been this reverse chronological timeline forever and having actual human beings curate things at scale would be a big challenge. i do think that'll help to surface the best content that is available. emily: sarah, what should we read into this given the leadership changes happening at twitter with dick passing the baton to jack dorsey as interim ceo? is this a change in vision even though jack dorsey has been saying there will not be one? sarah: this is something that dick has been working on for a while. actually, jack dorsey says he supports this. whether the new ceo comes in -- that is if it is not jack or someone internal -- whether that person comes in and says i don't like the strategy and let's do something different, i don't know that would -- it could completely change everything. for now, this is going in line with what investors are telling twitter they want. they want information organized around live events. you were talking about video. they could stream award show

change is coming. i wish it would have happened 65 years earlier, but it will help generations there here on out. >> one of the arguments before the court was whether this was changing the institution of marriage. and it was argued that by doing so, you would somehow jeopardize a family model that has been accepted for melinia. what is your reaction to that? >> that is a bunch of bunk really? that was one of the early arguments that opponents used. they used it in massachusetts, for 12 years now. it was one of those scare tactics. now it's this whole religious liberty argument; that people will be forced to do something against their will. they are really grabbing at straws. we have seen organizations that have used this to raise money and to brutalize and terrorize americans are going to have to go off on a few other issues. so i'm very encouraged by this decision right now. >> fred thank you. i want to go back to roxana saberi outside of the stone wall inn. as the hours have gone by we are starting t

we can't just have small changes. there are changes going on.ght now, i will, south dakota, that 30% almost of all of their electric tower from wind. but we need to change not only electricity, but transportation, heating and cooling industry and electricity is only on the order of 20% of total energy anywhere. but states are making progress. new york has made progress by implementing some policies that would get us toward -- closer to renewable economy. there are some states like washington state that already have like 73% of their electricity is already from clean energy, mostly because they have a lot of hydroelectric. we need much more aggressive measures because the arctic cia's is expected to disappear within 10 to 30 years and that would cause acceleration for climate change. we can't wait 20 years for some new energy technologies to come around. we need use existing technologies today, implement them, and get the ball rolling in terms of the transition. amy: people still raise their out brawls we windmills, when you say solar panels, the

if the rain changes, they're really in trouble. think the richest countries in the world that are here have an obligation to help poor people in poor countries adapt to climate change. we are calling on them to make commitments in copenhagen. leaders have said they would provide $100 billion the year to make these transitions. so far that money has not been coming. juan: on sunday, what a spokesman josh earnest will reporters -- told reporters they discussed greece at of the g-7 summit. >> as a relates to greece, i will say there is anonymity of just you nanometer the -- unanimity of opinion and greece and their partners to chart a way forward that built on crucial structural reforms and returns greece to sustainable long-term growth. we are pleased that we've seen some are indications from the greek government and there obviously is a deadline that is looming and the president certainly hopeful that greece and their partners will be able to chart this path without causing undue volatility in the global financial markets. juan: eri

you are talking about changing the rules and wasn't the rules changed for independents in the debates after ross perot? host: he did run as an independent. guest: yes, no, what happened back in the late 1980's and during the 1990's, we had a different group of criteria factors to take into consideration. the advisory committee led by professors at harvard with some academics and other parts of the country and we looked at many different things. the organization that they put together, how much money they had raised, how much space they were getting in newspapers. there was a whole number of factors and ross arrow meant those criteria and the recommendation of the advisory committee to us in 1992 and was invited to dissipate. he did not meet that criteria in 1996. we then took a hard look, we always do, we took at the criteria again and said, we want to be as objective. the law requires us to have an objective standard and therefore, we thought it was a little too much subjectivity in what we were doing previously and we thought that the 15% role in the five leading polls an average wa

the earth is changing. like the german before was talking about, the nuclear power plant melting, that is not nature, that is a man-made problem. we have got to protect the earth. no matter what reason the earth is changing, you have to admit it is changing. it is harder -- hotter. the ocean is nasty. we have to protect there is. -- the earth. host: if you want to hear the thoughts of another presidential candidate, rick santorum is expected to appear on "this week" this morning and is expected to address the popes's encyclical on climate change. kevin is in hobart, new york. caller: good morning. first off, i'm very impressed by your last caller. it is very weird to hear a republican talk about climate change that way. it was very impressive, and we need more of them to speak out. the pope is going to say what the pope is going to say. some people are going to listen and some people are not. the likelihood of a changing our politics is slim to none. we have our politics in the hands of corporations that pa

'15, '16 proposed. >> this is the general fund change by year. on the revenue -- my question is a revenue question. we don't need to look at this. where are the risks? when you sit back and like, what should we and the public understand about the revenue risks which are going to drive? >> that's a really good question. i was looking at the wrong slide. i believe at the lot of that revenue variance is due to sale of debt to funds some of the expenses associated with the rebuild. it's not your classic operating revenue. it does show up as a misleading variance. that's a really good question. we have couple of significant risks that are out there. the first one that comes to mind, we have a new 1115 waiver that's currently under negotiation. depending on how the outcome of those negotiations happens there are two things that could happen. one is that we could have a different slice of the pie. we could have a different percentage of what we take out of those waiver dollars. the other is there could be more hospitals essentially completing for those

climate change is also bad for people with seasonal allergies. about 30% of all americans and roughly 10% of americans with asthma. warmer temperatures lengthen the pollen season because plants bloom earlier in the spring and also higher levels of carbon dioxide increase the amount of pollen produced. in the northern states of the u.s. pollen seasons have lengthened by more than two weeks today than they were in 1995. and they are also more powerful. studies have found that when pollen levels are higher, people use more medications and visit their doctors more for allergy. emergency room visits for asthma among children and adults go up. and one of my patients who is a single mother with a teenage son, both of whom have severe asthma, called me on a weekly basis this spring because of trouble breathing. and between the missed days of school for her son and missed days of work for her, this allergy season was a disaster for her family. i'm a physician and a researcher, but my most important job is my role as a mother to three children under the ag

you are seeking to change what the institution is. core of the institution is the opposite sex relationship you want to introduce a same-sex relationship. >> if you are talking about the fundamental right to marry as a core male-female institution the fourteenth amendment provides guarantees that what was viewed as the role of woman, with the role of gay people even, has changed in our society. just as the lawrence court called out the other court for not appreciating the liberty at stake, the same thing is whether gay people share that same liberty. >> one of the problems is when you think these cases, you thing about words and cases. first of all, there hasn't been time so the respondents say for the federal system. it is about the same time between brown and loving as between lawrence and this case. and that is ten years. that is time for scholars commentators and bar and public to engage. but i don't know how to count the decimals when we talk about millennial. this definition has been with us for millennial. and it is very diffic

and pope francis is expected to talk tough on climate change. how seismic and powerful a statement is it that he is dedicating his encyclical to this one topic? >> reporter: well, that is the keitha he could have written about anything, he chose to write about the environment and chose the use the highest teaching document available to him, the encyclical. clearly he means it to be a top priority and wants everybody to listen. as you mentioned yesterday he gave us a preview of what we might expect from the document when he said that climate change is affecting everyone but especially the poor. so from that we can assume that the pope, who has already been a champion of the poor is going to draw the lines between climate change and the responsibility of individuals, of big business, of governments and finance to take care of the environment for the effect that climate change can have on the economies of poor countries, errol. >> when you look at what the climate change panel at the u.n. has said is that as sea levels rise low lying areas will be

not too long ago the scouts changed the policy that secluded youth leaders. roger ganum. one of the things that the option. that is some sponsors saying we will be a troop that doesn't welcome gay leaders while the troop downed the road may take them on. can you live with that? >> well, i think it's not a question of whether i could live with it. we know that the groups pushing this homosexual inclusion agenda on the boy scouts such as the human rights campaign are on record saying that's not good enough for them. so this fight will not go away by extending a local option. the other problem with that is this: scouting rose to greatness with this help and support of churches and religious organizations that hosted scout troops. now typically those organizations are exempted from local nondiscrimination laws regarding sexual orientation because of their sincerely held religious beliefs against homosexual conduct. if the organization such as the boy scouts adopts a permissive policy against homosexual conduct, it is going to put churches in a position of potentially secludin

jerry hill: they've said they're going to change they've committed to changing, but they haven't changed. announcer: we area news special. tonight, we investigate. >> they said they're going to change. they have committed to changing but they have not changed. >> we investigate security at pg&e. we have the link to the internal memo that talks about the situation. we investigate emergency preparedness at silicon valley's airport. why some question san jose's resources when it comes to handling a crash like asiana. >> it's terrible that they decided to sell this in their meat case. >> rabbits, sold as food. the controversial new protein at a major food chain. why the producers may not be meeting quality standards. >> thank you for joining us. for the next 30 minutes we investigate. what does that mean? it means investigation that gets results, following your tax dollars and holding the powerful accountable. we begin tonight with an internal telling memo about pg&e and its critical sub stations a memo the company never thought you would see from pg&e's director of corporate security. and w

it's been an incredible change. the city has grown and changed so much. it's a very welcoming place for the lgbt community now. good to see that happen. >> now the state will change in a dramatic way after today's decision. >> right, i hope so. i think now that this has happened, i think not just ohio but across the country as people see more gay couples get married, they're going to realize we're no different than they are. and i think it's just as this becomes more open, more visible, people realize we're simply asking for the exact same things. so love and commit to the person we want to. so i think the state of ohio and the rest of the country will see changes for the positive. >> jeffrey toobin, anything else you wanted to ask? >> that's really the point i wanted to make because it's such a dramatic change. this was the city that prosecuted the local art museum for showing robert maplethorpe photographs. photos of homosexually oriented photographs. now jim obergefell is like the first citizen of cincinnati. that symbolizes not just cincinnati's chang

the way it approaches climate change. >> right we have good answers to things like climate change and we suffer with an inferiority complex that we need to over cox. -- overcome. it's a matters of fixing the environment and the climate will take care of itself. >> how likely is it to see change, as we go into a conventional year, unless you stick it the conservative orthodoxy, the manmade events are not leading to climate change, that you can't get through the primaries, because it's the conservative base that shows up to vote. and most american conservatives do not believe that climate change is the result of manmade efforts. >> that is changing because young conservatives are with us. we at republice..org. that is coming our way, and the other thing it the recession is leading us people are able to focus. then we benefit tremendous from things like the pope's issuance cyclical making a game changer. doesn't the popes and cyclical create a difficult dilemma for some of these candidates as they move forward. the pope is not as popular among conservatives as among others in this countr

and so what are the major changes? and the major changes, proposed include, 5.1 million, and in the new general fund initiative. and 2.9, was added for the new enhanced residential cleaning program, which will provide lower noise and over light cleaning in the blocks in the soma and china town and the mission and the polk street neighborhood and the budget also provides, 927,000 to continue to expand the successful pit stop program, with new funding and we will keep the -- we will keep the four existing pit stops so that we have and we will add, a few new locations, and we have started a pilot by adding some monitoring to the free standing toilets. and this will free up the manual cleaning crews to address the cleaning needs in other neighborhoods and as you know and you have heard me say many times and many of the staff get diverted to other areas and with these initiatives that will help us go back to some level of civilization and address some of the challenges that the department faces. >> and as part of the budget

history and they can't change it becausean' they can't change the truth.and the woman who was on the last segment in terms of support the confederate flag which was totally against -- the black woman, i would like to say to ut lou her shed screams out loud there e were people in the south killingling blacks but it was the northern people and the millions and millions of lives that put their life on the line for the blacks put to free the slaves and that is the most ironic thing that i canblacks say to the blacks today. the other thing in regard to gun control which i like to bring up is just think i would rather see america more armed than less -- armed because isis wants to come isis in or russia wants to come in hereond attack this country or china, have at it. because they're going to see one hallacious -- you think the war in iraq was something awful or ireland, wait until they come to america and see what we do this them. >> ann colter several topics to choose from. >> yes. that is right. 600,000 white men died to redeem the principle that all men wer

that could change in the third year. if we think it will not change, making insurance cheaper for them and more expensive for the older enrollees would pull in some of the younger folks. that's a priority. >> i know the employer candidate was controversial. wasn't it a device for getting people into the risk pools, and that was supposed to push the cost curve down. >> it's a little more complicated than that. the way that the risk pools work, is that insurers separate market. they are treated separately and the effect of the employment, the mandate on insurance is likely fairly minimal. the urban institute did research on this, they said it's about 500,000. the c bo has their own estimates. it's low in the grand scheme of things. you could theoretically getrid of the employment mandate and see relatively similar coverage levels without the effect of the mandate. >> i'll be back with potter. republicans in congress and running for president will not have to find an alternative to obama care, and replace subsidies or reens

started to change. they knew the massic mistakes that came to a head with the election between sepp blatter and the man who was banned from that point on, they couldn't continue like that. the big change that people then wanted to see is was eventually going to get his and he has done that. >> let's bring in tom ackerman our man in washington d.c. of course, we are talking about a justice department, inquiry. an fbi inquiry last time i heard there were leaks from the justice department, in which somebody unnamed was saying you ant seen nothing yet. well that very well may be, we have not heard anything official or open from the u.s. soccer federation, or from the justice association. but what is really interesting here are the repercussions on the actual world football schedule. the u.s. is due to host the 100th anniversary next year. and as you can recall, the indictment said alleges that hundred million dollars in the bribes were payed to assure the selling of the broadcasting rights to for this year.

it is a very dynamic change. we still don't know what that second bump is or what role it plays or whether boys are born without test thesees and show any differences because of that. the problem, eric ,is, is that when we want to look at hormone we want to measure it. you cannot get it out of the brain. the other problem is sometimes it is not the hormone level that is important but the affinity of the receptor for them and it is very difficult to measure such things. eric: it is a very fascinating problem. to see what is the biological underpinning of entity. it is so important because kids who were in the wrong sex their incidence of suicide attempts is serious. norman: it is one of the highest risks of any. eric: it is something we need to understand. norman: in the puberty process this system reawakens again. the system that has been awakened in utero comes back in which hormones hitting the pituitary causes the release of other hormones that strike the ovary or testes and cause the release of testosterone o

you seem to have changed your mind. why? senator corker: the agreement that keeps iran's nuclear weapons -- we were able to pass out of the senate a bill that allows for whatever happens with the g5 was when negotiations. what i'm responding to directly is concerned that corners may be cut, especially relative to the dimensions of what iran has done . it has always in something -- understanding what their capability is. the other pieces making sure any time, anywhere in the process, we have been getting word that may be a bureaucratic process would be set up like what happened in iraq years ago. we are wanting to make sure that as we get to the end, we and that was not erosion taking place in this particular deal. that's why we have had the discourse we have had over the last several days. reporter: your letter is very frank to the president at you also say it's only the people at the table who know exactly what is going on in these negotiations. so how confident are you that the work you are getting is accurate? senator cor

and make changes. this is about making changes. "america tonight" - lisa fletcher is here.nie did not get repatriations. others did. will this be enough to close the chapter. >> that's what a lot of victims are asking. they say this is a nice first step. and when you look at the repatriations deal. financially it doesn't offer that much. 5.5 million, divided among ex-amount of victims, i know there's a cap on what each victim can receive. if there's more victims than money, they'll shrink the dollar amount done. here is interesting things that go with the reparations that go in addition to the money. job training, counselling. there'll be a memorial to the victims, and a public school curriculum on the john burge era, in the hope of not repeating this thing. >> it's satisfying, for these many that lost so much of their lives, is it satisfying to think there'll be education or whatever money there is. >> someone more excited about the education combonnet. they'll carry on into the future. for most of them they are saying the money is so small and meaningless compared to what

it can be changed with right leadership. >> if you can't change it from the inside you can't change ite. >> yes, we can bumper stickers to put quotes around the we part. he is trying to change grammar. >> it is your fault. >> i'm just a little bit confused about you who you protect your legacy if you don't own it? >> he doesn't own anything though. he seems to have forgotten he has been president this entire time. i understand, governor, people who bought the story the first time, i can really understand that i saw a lot of people who saw him campaign in 2008. they were touched and felt like this guy could bring hope and something new. he was an outsider. a lot of people bought that story again the second time. >> so ridiculous when you think about it. essentially throwing people who supported him under the bus. think about the arrogance. it is not me. all on you. i mean, does he own as harris said anything? does he own any responsibility? >> yeah. >> he owns responsibility. i fear that is why they're pushing so hard for this iranian deal that will be a cornerstone. i think it will be

who changed their minds about it. and it was not an objective position. look at the child who is more vulnerable than two sexually transmitted disease, deadly diseases like aids as a result of participating in a lifestyle of homosexuality. >> that is a different issue. >> no it's not. it's sexuality. >> why should parental rights trump the psychological associations standards about protecting children. >> why should parents rights be trumped. what about children not taugh to... >> but isn't it child abuse. >> child abuse is in the classroom when they are told lies about the american psychiatric association, and the conclusion that it drew when it was skewed. children are taught and led into believing that this is a natural and normal and healthy lifestyle. when the fact is no nation on earth has ever said we are going to put homosexuality on the same level as heterosexual marriage. now america is considering this. it's the wrong drerks. what we have seen, yes, there was a decline in morals. towards the end of the empires. in the united states of america,

what has changed. >> well, our tactics, training. we do everything we can to make sure that officers only resort to deadly force as a last resort. they do have tasers available to them now. oc spray. less than lethal options, sws a lot of focus on de-escalation, using words in order to de-escalate a volatile situation. anything we need to do to bring a situation under control. fortunately, so far, we have been able to see a friend downward. >> there are no - you may have heard me say this, there's no standard on the use of deadly force by police officers. stay laws do not require deadly force. nine states, including washington d.c., where the police chief have no laws on the use of deadly force, is it time to spsh a law or understanding national lay about when officers should use deadly force, or not? >> well, i mean, we have 50 states and each has its own set of laws governing police use of force. i don't see that changing any time soon, there's different nuances in the law between states and so forth. i can tell you this. the major
