buenos aires. >> i'm randall pinkston, thank you for watching. john siegenthaler, is right now. >> during the site of the rampage, fbi is looking more closely at whether the married couple behind the attack had links to terrorist organizations. john terret reports. >> slowly and methodically, the fbi says the shooters,ed farook and tashfeen malik may have entered this area. the fbi hopes to find evidence the couple may have left behind or tried discard including digital clues that may reveal the motive for what investigators are identifying as

a terrorist attack. >> we would be remiss not to go into this lake to do a thorough search for any evidentiary dwhraits might comitemsthat mig. >> enrique marquez bought two of the rifles used in the san bernardino attack. farook and marquez abandoned their earlier attack plans after the arrest of four men who were arrested. >> there have been arrests immediately adjacent to that, right in their area of southern california probably by the counterterrorism people that really caused him them to rethink it. >> the fbi says it is investigating the men. despite farook and malik's online chats b about jihad and

terrorism, they were able to obtain a fiancee visa for malik. >> if we know it now why didn't we know it then, when she went through wonderful vetting process? >> john terret, al jazeera. >> obama administration's underfor propaganda, in washington, d.c. ambassador, you called the administration's response to san bernardino flailing and tone-deaf, why? >> i think the problem is of course that the administration has a policy on i.s.i.s. and on the middle east and of course, it's been hitting certain points that maybe have a certain logic about containing i.s.i.s. and degrading it and destroying it. and so it was for the moment it was certainly jarring.

you know you have this rhetoric of success, basically, which this great tragedy, so it just sounded wrong. that was the tone-deafness that i saw. >> and taff sheen malik posted allegiance to i.s.i.l. the day of this attack and was active on different sites. you called it do it yourself jihad. could anything have been done to stop this attack? >> well, there are certain elements in the attack which are predictable. there are others that are unique to this attack. for example, the husband, mr. farook, was a member of an at-risk part of the population. second generation immigrants. not an immigrant. not a refugee. but their children. especially coming from broken homes and all of this, there's a whole pattern of this being an at-risk population, second generation muslim immigrants. not their parents. the husband, wife with the

little daughter situation is extraordinarily rare. so there are some signs, there's obviously, they were talking to people on social media, so there were some things which were predictable and some things that seem very unusual and that we still need to get all the facts on. >> so how does that change the war on terror? >> well i mean what it does is if we needed one, we shouldn't need one, it should be a wakeup call and that i.s.i.s. is a very interesting situation. it is slowly being weakened in its heart land of syria and iraq. the physical state is under a lot of stress. but the i.s.i.s. brand, the i.s.i.s. idea, the i.s.i.s. way of doing things, you could say the jihad lifestyle of i.s.i.s. has kind of met as at metastas. it has entered the bloodstream of a small percentage of the total population but it's a significant number of people that find it attractive.

has elements that are compelling, and powerful, for a small subset of people. >> you had a staff struggling to compete against i.s.i.l.'s vimps virtue onlini.s.i.l.'svirtual o. were you outnumbered? >> i.s.i.s. helpfully released a couple of weeks ago their summation of work for the year. they produced almost 1800 videos in a 12-month period. they produced 15,000 graphics. they produced 30 songs in nine languages. so this is a media colossus. they are both in the news -- >> how are you competing against them? >> you need a network to fight a network. you need to find a group of people, a large community of interests, that at the very least is going to try to push back on them in the same spaces they are. the best way to weaken them is

to weaken them militarily. to see the state deteriorate and be destroyed. that is the most powerful propaganda message you can send. >> what is it about the message that resonates? >> it is the language of revolutionary. it is about youth revolt, it's about empowerment, it's about rebellion. one of the paris shooters, we just did a report on him, in memory, he said a year ago, he said, now is the time for the oppressed to rebel and revolt. obviously, people living in france weren't too oppressed but they thought they were, they felt that way, they were filled with resentment, they felt they needed to do something and be part of this large utopian vision, this state-building project. it is about youth, empowerment, personal fulfillment and about

this vision. not unusual. nazis had this vision, vision of building things. communists are have this vision of building a bright future so it's not actually that unusual in the history of mankind. >> ambassador it's great to see you, thank you for joining us knit. >> thank you. >> in switzerland tonight two syrians are reportedly under arrest and the whole country is under alert. not clear if the two syrians are part of that, according to reports police say they have trace found traces of explosives in their car. the hacker anonymous urged its supporters to go to social media accounts and make fun of i.s.i.l. the group also claims to have nearly taken down the website for donald trump's trump tower sky scrape are in manhattan.

republican presidential candidate bn ben carson has threatened to leave the party. angry at a meeting, some power brokers argued if donald trump wins the primaries the establishment wing should rally around an alternative candidate. >> i think party should not be doing anything that is deceptive and under the covers and that twarts the will othwarts the wi. >> are you hope? >> traditionally i hope we have had stronger leadership than we had in the past. >> carson said i will not stop by and see a threat.

we the people not they the powerful. donald trump said if he is not treated fairly by the republican party he will consider running as an independent. and we're learning more about what americans think about donald trump's proposal to ban muslims from entering the us p a new wall street journal poll says nearly 60% oppose the item. 42% of gop respondents support trump's idea, 36% oppose it. linda sarsur, back in our studio tonight, linda welcome. >> thank you for having me. >> what do you make ever that poll? >> it really scares me that 42% of the republican party actually supports the banning of muslims to come to america. i mean it's outrageous, first it's unconstitutional. but to feel that people actually support that is a very scary

thing. >> you said these are not just words but they've had a powerful impact on muslims across the country. talk about your own experience? >> i mean unfortunately what donald trump and others are engaging in is hate speech and it's insightful hate speech. just today there was a fire bomb in coaxella, california. a deli owner in manhattan, in astoria beaten add bloody, have nothing to do with any terrorist attacks. living here americans in this country. >> and you relate this to donald trump, why? >> i relate because donald trump's speech is insightful. hate speech. when you call for a man who is calling for registration of muslims, they are cheering on an american fascist, that really scares me. words can influence people to commit acts of violence against

neninnocent people. >> what is your message to donald trump? >> our message is, he's not going to divide us. what scares me more than donald trump is the people who support donald trump. who is actually going to vote in this election? i'm calling on people of conscience, to say this is not the america i want to live in or my children to live in. >> you have talked about this on this program over the last six months. what's changed since six months ago until now, about the way -- about isla islamophobia today? >> today versus six months ago, i'm going to say it again, we're living in the most hostile civic environments even in the weeks after 9/11. we would never allow the type of rhetoric that's being spewed by pundits and some media outlets

and candidates like trump. we would not allow it by any other group but we're allowing it against muslims. >> you were upset about president obama's comments. why? >> because the muslim community has always cooperated with law enforcement. president obama was acting like he's enlisted us in something that has never been done before. we care about our communities and our country and we should ask all people to be rooting out all forms of extremism, including muslims. >> you've heard people close to this couple in san bernardino that may have known things and didn't report it. is that a problem in the muslim community that muslim americans are afraid to come out from behind the shadows or don't want to? >> i don't think that's the case. 40% of terror plots in this country have been thwarted by muslim americans. to put the entire responsibility

on muslims when we find white supremacists and terrorists shooting up planned parenthood. >> you received hate mail. talk about what they say. >> it's really some of the most hateful ugly have i vitriolic ts i've ever heard. telling me to go back to my country. my country is here, brooklyn new york. telling me to go get raped. i tell them that this hateful rhetoric is exactly the hateful rhetoric that i.s.i.s. engages in. hating me is not going to save us from terrorism. it's uniting and seeing your fellow americans, muslims as your fellow americans. that's the way we're going to fight terrorism in this country.

>> linda, thank you so much for being here. >> thank you so much for having me. >> martin o'malley visited a mosque and community center in virginia, referring to trump as an unscrupulous he said trump and others politicians like him are trying to tear america apart. o'malley is polling far behind hillary clinton and bernie sanders for the democratic nomination. damage of a southern california islamic mosque today. fire contained to the front lobby. the mosque leader says people who were there at the time believed the fire was intentionally set. the mosque was also hit by gun fire back in november of 2014. canada is welcoming syrian rfertion. threfugees. the first group was flown in

helped them leave their war torn country and how life the coming along. >> they'll help you to find work, help you navigate the new society you're in. what's that been like so far for you guys? does it seem very different here? >> yes. >> i mean in general, it's very different. but the community prepared everything for us. i mean they introduced us to the society and step by step what should we do to be integrated into this community. they provide us everything, homes and food and everything and helping us find a job. >> their home destroyed, schools bombed, friends killed and a daily suffering of fear, threats and eruptions of war at any moment. but one thing is certain in khan

al mosri's life. >> it's not about opinion, about where you're from, it's about humans. >> humans. >> what's your take? >> what i'm thinking about is, as my father said we're all humans. humanity is what gather us together. it's not about religion, not about you're black or white or anything else. just the morals you have to be, you -- it's the religion is how to treat your brother. how to treat your neighbor. so that is not religion issue or black or white. it's not like this at all. >> father and son. sitting. in peace at last. a future with promise awaits young najeeb, who hopes to study engineering and architecture, with the dream of rebuilding his

>> protesters in chicago are calling on mayor rahm emanuel to step down over his handling of la quan mcdonald's shooting. for the first time the video of the shooting was released. andy rosegen is in chicago. andy. >> reporter: after three and a half hours the protests are finally wrapping up. 75 protesters blocked these major intersections around chicago but mostly peaceful. there were some minor scuffles with drivers who tried to break through. the police kept their distance

in all this but earlier today a big significant development was when the family of la quan mcdonald finally talked. they had not talked at all since that video of their son was released. he was shot dead by an officer in 2014 and here is what his great uncle had to say. >> so these people are marching because time and time again, black people and people of color and poor people are being mistreated by this legal system here called the chicago police. >> reporter: he also said that la quan mcdonald's mother has not been talking at all, tina hunter. she's been crying and hurting quite a bit on this and that's why we haven't heard from her john. >> a lot of pressure on the mayor. so what's been his response? >> reporter: so far just a big

apology on monday. but almost nonstop from so many different groups, medical students, there have been bishops, members of the county commissioners all nangd several things, not only his resignation, the resignation of the state's attorney, also they are demanding that all the police videos that are currently under wraps in police involved shootings be released, a variety of things but mainly they want the feds to come here as the department of justice said it really would, to shake up the police department, a change at the top a systematic change john is what they want in dh chicago. >> all right, andy thank you very much. freddy gray died after being in police custody. william mcdonald answer trial has concluded. prosecutors say police failed to

place between december of 2013 and june of 2014. unlike the officer's other victims all black women in areas holtsclaw was assigned to patrol, she helped prosecutors break open the case inspiring 13 victims to come forward. >> he picked the wrong lady to stop that night. >> an all white, two-thirds male jury found holtsclaw guilty on 18 of 36 counts, delivering the verdict on his 29th birthday after four days of deliberations. >> the defendant is guilty of the crime of sexual battery and set punishment at eight years. >> the convictions are associated with eight of holtsclaw's accusers. holtsclaw was found not guilty of charges from the five other

she had been intimidated by the officer's badge. >> this is the face of courage where people dare to stand up and say we refuse to remain silent so we applaud you all, we thank you all. >> holtsclaw could receive up to life in prison, at his sentencing next month. the jury recommended 263 years. heidi zhou-castro, al jazeera, dallas. >> the newly released video of are supreme court just scalia's statements from the bench. holding up a long term spending plan in congress.

>> hi everyone, this is al jazeera america, i'm john siegenthaler. on tape. taking on affirmative action. the tape of supreme court justice antonin scalia. sea change, why it may be a greater threat than cliemtion. than climate change. and what d wait until you ht the photographer says about th this. antonin scalia implied that

african americans might do better if they went to less challenging schools. the supreme court released audio from that session. >> justice antonin scalia indicated perhaps the university would be better off with fewer african american students. >> there are those who contend that it does not benefit african americans to get them into the university of texas where they do not do well. as opposed to having them go to a less advanced school, a less -- a slower-track school where they do well. i don't think it stands to reason that it's a good thing for the university of texas to admit as many blacks as

possible. >> and this court heard and rejected that argument with respect justice scalia. >> reporter: reaction was fierce from the courthouse steps. >> i don't know if i was in the courtroom at the united states supreme court or at a donald trump ra rally. >> reporter: democratic lawmakers and others called the comments troubling. some suggested scalia recuse himself from the case or even step down from the court. scalia's comments were based on something called the mismatch theory that students who get into top schools through affirmative action play not be prepared for such a rigorous environment and do not do well. those behind the theory insist it is a well researched and documented problem. others don't agree. >> there is simply no data that students of color admit through affirmative action programs are

anything other than leaders in the making who are going to succeed greatly in school and out in the country. >> reporter: ultimately it is not what the studies show but what's what the justices think. the chief justice wondered whether it really matters if every university classroom is diverse. >> what unique perspective does a minority student bring to a physics class? >> your honor, the attorney not the university said, this court has accepted that student body diversity is a compelling interest. lisa stark, al jazeera, washington. >> president obama today signed a short term funding bill that keeps the government running past the midnight deadline. but the congress has only a short time to agree. libby casey has a report from washington.

>> pushing off voting until next week. >> mr. speaker i'm hopeful that on both sides we can see that which is unacceptable to the other side and put that aside for another day. >> reporter: congress buying five more days to hammer out a $1.1 trillion package. negotiations happening behind closed doors. complicating discussions controversial riders that could be tacked on to the deal such as halting the obama administration syrian refusing program, something that republicans want but most democrats don't. tightening the visa waver program. another controversial issue, the crude oil ban that's been around since the 1970s. democrats are pushing to end a ban on research into gun violence and then there's a fight over renewing tax cuts that are set to expire. some republicans want to make those cuts permanent and roll in

a tax extenders deal but that could cost over $700 billion over a decade. >> i think it's far to expensive. >> i think whatever comes out of those negotiations, would be a bipartisan vote. >> reporter: the white house is sending off on the short term extension but warns congress it needs to pass something next week and not delay yet again. >> without a deadline, congress doesn't do anything. we've got to have a deadline and the president is going to insist on one. >> spokesman josh earnest. >> funding levels or other things that we don't enthusiastically support. but the president's not going to

let a disagreement over one issue become a deal breaker over all the others. >> reporter: most members of congress are playing a waiting game osee what ends up in the final bill. the house does not have its next bill scheduled until tuesday evening leaving very little time until members head home for the christmas holiday. libby casey, al jazeera, washington. >> ray lahood, the former transportation seark, on secrets just written a book, i. >> what happened was, there was a very, very bad economy that the president was t hear iting when he came in, in '09, he focused a lot of attention on that. within 30 days of his

swearing-in the congress passed an $870 billion stimulus bill. and the president then really continued to focus on that, and he also had as one of his goals to get out of iraq and pass national health care. there were some attempts by his new chief of staff, rahm emanuel, to reach out to republicans. but it became clear that it really wasn't going to work. >> then who do you blame for not working congress or president obama? >> i think there's plenty of blame to go around. i think that the president tried in the beginning. i think it became clear that the democrats had the votes to pass whatever legislation was on the president's agenda and i think it became clear that republicans realized they weren't going to be players. and they became very stubborn also. when given an opportunity to be players, particularly on health care, particularly on some of

the national issues with respect to getting out of iraq. it just -- it wasn't going to work. >> since it's failed, why will it succeed or why would it succeed in the future? whether it's a republican or a democrat in your opinion? >> well, it takes people who are willing to work together. it takes people that are willing to sit down and develop the kind of relationships. our 236-year history in this country has been about solving problems, whether it's civil rights, whether it's medicare, whether it's social security. these things were done in a bipartisan way because there were relationships that were built across the aisle, across parties and until that really begins to happen in washington and i think if you look at more recently the congress did pass in a bipartisan way a transportation bill. the president just signed a very -- within the last few days an education bill that reformed

no child left behind. a bipartisan bill. they're working on a bipartisan trade bill. there is a little glimmer of hope here that perhaps some major things, a couple of them have already gotten done and maybe a couple of other things will do. >> it's presidential election year, donald trump is leading the republican party. what does it tell you about establishment politics in washington? >> i think what it says more about is that the american people right now are -- really believe that problems cannot be solved in washington. that the people that are charged with responsibility of taking on the big issues whether it's immigration reform or tax reform or other issues, balancing the budget are simply not addressing those issues. and so they are looking at people who have traditionally not been involved in politics. i.e. donald trump and others. and so i think that the dissatisfaction and the

disenchantment and the disenfranchised public feels like maybe we ought to turn the reins of government over to somebody who has not really been involved. >> if he's not been involved who will be the nominee for the republican party? >> i don't think donald trump will be the nominee. he has turned off so many groups in the country whether it be hispanics or muslims or women, it's not the concrete views, and in the end republicans will decide on one or the other people that i think are in the race, and have offered very strong solutions. >> good to have you on the program,. >> thank you. >> details of a plan of a $130 billion merger, in what's been

billed as merger of equals, investors would be given shares of both companies, called dow dupont. the plan is expected to face some tough scrutiny by federal regulators. two top fantasy sports websites from doing business in new york. earlier today a state supreme court judge ordered fan dual to cease operating. the two fantasy sites have time to submit arguments in court. mary snow is in for ali tonight, mary. >> john we're looking into police departments in the country to make changes in their use of deadly force. we'll bring you the aftermath of

>> climate talks in france were extended after china and other nations famed to agree on carbon emissions. diplomats are trying to decide if and how to pay for climate change and on a global scale. france's foreign minister says he's hoping for a final draft on saturday. the same greenhouse gases that are causing climate change are affecting the world's oceans and on the u.s. west coast, the seafood industry is suffering because ocean water is becoming more acidic. allen schauffler explains. allen. >> good evening john, a problem two centuries in the making, a problem they've recognized just in the last decade or so and just beginning to study seriously. now it was west coast shellfish growers, oyster farmers who felt

the first impact of this and were first to sound the alarm. 3 million pounds a year grown shucked and sold at goose point on washington am wilipa bay. kathleen is a young coo, due to the changing chemical composition of west coast waters. >> it's changed the way we do business entirely. we have a whole new business now because of ocean acidification. >> the ph level, the measurement of acidity, the researchers of noaa,. >> there hasn't really been a time in history that we can observe, that we can detect where the co2 has changed this

fast. >> reporter: so we realize don't know what's coming? >> we don't know exactly. >> reporter: we know more co2 means more acidic water and the effects are dramatic on the west coast of north and south america where seasonal currents cause up-well, with deeper waters which stores carbon dioxide in higher concentration. man made co2 trapped in the water. >> a lot of the species that lift live ilive in the ocean ar. particularly those that make shells. >> we were going to suffer and die or come up with another solution so our company could be successful in the future. >> about eight years ago, seedling oysters started dying. researchers linked that to high

acidity. kathleen sees more than farming and oysters at risk. >> i've got 85 employees that rely on me. we're huge part of the community we're in. if we're not going to adapt we're out of business. >> so goose point built a new hatchery in hawaii where a saltwater well provides consistent predictable water conditions. seedling oysters are sen sent iy air. >> can you fit about 1500 in the palm of your hand. >> less traffic way of managing the waters. the oyster scare is likely just the beginning. studies show tiny sea creatures are vulnerable to acidification. etched, damaged shells could weaken the species with consequences up the food change. >> those effects ripple through the whole food web and can

affect ultimately the salmon we care about eating and the orcas that eat the salmon. >> researchers say we have done this to the world's oceans, that leaves one question unanswered now, is there any realistic way we can undo it? reducing carbon eapplications would help, but even with significant reductions it could take centuries to get back to the ocean chemistry of 250 years ago. >> if you are 92nd adapting you're dying. >> we'll have to learn to live with changing oceans. >> there are still going to be a lot of things living in the ocean. the concern is that the things that increase are not the things that are kind of important to people. >> i feel that it's going to be a really bumpy ride and it's going to be scary at times.

>> once again much more study is needed. and exactly how long it might take for dramatic impacts down along the food chain to take effect and for us to see them is really unknown at this point. paul mcelhaney's studying the effects of more acidic water into 2050 and to the end of the century. most certain is the change is coming john and we'll have to adapt to it. >> given all this how is the oyster industry doing now? >> you know they have found ways to adapt at this point. and they're doing okay right at this point. goose point for instance growing its seedlings in hawaii and shipping them in. other west coast oyster growers doing a better job of measuring the ph levels and figuring out the times when they should or shouldn't draw that water into their nurseries. as long as they can figure out ways to get less acidic waters

into the nurseries and get the oysters through the first stage of life they're doing okay. they will all have to be ready for changes that might lie ahead. >> allen schauffler, thank you. scientists are using sophisticated brain distance to proof there could be a biological basis for religious devotion. religious neuroscience. crystal dilworth has this report. >> father, son and holy spirit. >> religious faith of the 7 billion people on the planet it's estimated that 84% are members of hundreds of religions. despite the different gods, philosophies and rituals, most religions share a promise for a physical sense of spiri spiritu.

>> for many who have never felt the spirit, can you try to describe some of the components to it? >> it is a very much pleasant feeling, i have clarity and burning throughout my chest. >> gow do you believe in your heart of hearts that you can scientific investigate something like faith? >> i'd like to think so. >> ariel's feelings made her a perfect subject. that's where "techknow"'s crystal dilworth picked up this story. >> what motivated you? >> it's the biggest story out there. >> 20 devout mormons, biologic

biologically tracking. giving a picture of the brain at rest. next is a functional mri, of airial as she is reading about faith. >> what regions of the brain seems to be most involved for her? >> the dorsal anterior cortex and the area called the insula. special brain work, noferlt novy network or the salient network. >> deciding what was worth responding to. >> your brain was lit up like a christmas tree. it was very telling how much the emotional response on your brain showed a lot of activity an in a lot of different regions. >> i welcome anything that embraces the fact that you have a physical reaction to that and that can be looked upon and

measured. >> for more on this fascinating story we turn to "techknow"'s phil torres. he's in culver city tonight. this report what was the point of it? >> hey john. first of all it's important to note they're not trying to prove the existence of god. a lot of people, when they see this kind of research, worry, is that the end goal? trying to pleasure what goes on biologically, and considering there are billions of people on the earth who are religious, scientists think it's important to get to know a little bit. >> on this study, they focused on devout mormons, why? >> honestly, the researchers live in utah and in the neighborhood there are a lot of mormons. what's surprising is people would expect that the community wouldn't be as accepting to join

the research. you don't hear religion and science getting along too along but they kind of embraced what each other had to offer and it turned out really interesting. >> how did the researchers make the connection between mormons and other religions? >> that's something they would love to be able to do. right now this is very preliminary, they're doing this proof of conceptual, can it be -- concept, can it be done? they want to get specific. they want to know what is the difference between the religious brain of somebody like mother teresa versus a radical fundamentalist. where do they cross paths and what difference is there? >> it is a fascinating story and for more on the effects of religion on your brain you can watch "techknow," five:30 eastern tomorrow. thanks phil. and coming up. the photographer tells us the

back story of these very excited donald trump supporters. qul

>> in our first person report tonight, one of the more memorable photographs of the year. it's donald trump greeting supporters at a rally in alabama. the picture was taken by mark wallheiser who tells us the back story about a much talked about image. >> once he arrived, it all starts happening kind of fast. i knew i wanted to get him on

the exit, as he left. because that's generally when they interact with the crowd. i saw the sign coming up but there were other signs too. and when i'm framing it through the camera you know i see the lady smile and her baby, what made it so special, is just the woman's expression. you don't see much of him at all and that to me was disappointing at the time did i the edit but then i also realized hey this picture is of the supporters not of him. i've been shooting quite a number of years. so the vile aspect of pictures has only come about recently. but this one has gone further than the others. you're trying to anticipate what's going on. yobut you really don't know what you're anticipating. it happens fast. >> that's our broadcast. thank you for watching. i'm john siegenthaler.
