arrest. so that's where this all starts to unravel -- >> so let me stop you again. no reason to chase him. no reason to arrest him. >> well let's go back to the chase -- that's a good point, tony. there's a supreme court case that says that police can stop and frisk individuals who are in certain high-crime areas. it doesn't say you can arrest without probable cause. so conceivably if they simply had chased freddie, stopped, had a conversation with him, determined that there was no reason no probable cause to arrest him, and allow him to go on his merry way, case over nothing -- no rights violated freddie would be alive today and we wouldn't be here talking about 28 charges against six officers. >> okay. so talk me through the treatment that the -- the 30 to 45 minutes that he was in this police van

and -- and what the city state's attorney described as to the events the lack of treatment freddie's conduct inside that van. talk us through that. >> so what we heard from the state's attorney is from the moment that freddie was arrested he said he couldn't breathe. so almost instantly he asked for medical care. it was refused. he is placed inside the vehicle. there is a stop that is made. the driver of the vehicle comes to the back of the vehicle, places him in some kind of leg chains. puts him stomach down into the back of this vehicle, again, he asks for medical care. it is refused by the driver of the vehicle. apparently the -- the van drives a little further, another stop is made. >> yeah. >> someone goes to the back of that van, again. freddie is in distress

throughout this entire time asking for medical care and at each point it's denied. >> so at some point officers have given a statement and signed the statement, correct? does that signature have the force of law? >> yes. >> so the idea that there was an unreported stop by all of these officers, or maybe a couple of these officers that's a problem, correct? >> a huge problem. >> all right. that's the last point i want to make. arreeva, what a pleasure always, thank you. >> thanks tony. >> yeah good talking to you. president obama spoke a short time ago about the latest developments in the freddie gray case have a listen. >> it is absolutely vital that the truth comes out on what happened to freddie gray and it is my practice not to comment on the legal processes involved.

that would not be appropriate, but i can tell you that justice needs to be served. all of the evidence needs to be presented. those individuals who are charged obviously are also entitled to due process, and rule of law, and so, you know i want to make sure that our legal system runs the way it should. and the justice department and our new attorney general is in communications with baltimore officials to make sure any assistance we can provide on the investigation is provided. >> all right. let's get you to john terrett now in baltimore. john maryland congressman elijah cummings spoke earlier. tell me what he had to say about

these charges. >> reporter: well you know, elijah cummings is a remarkable man. he is 64 years old. he is the congressman for the district where freddie gray lived. and every night since the curfew has been imposed he has been there. he has been in the crowds. helping members of the church community and other community groups to calm things down saying things like go home. the curfew is coming. don't stay out here. don't agitate the police. he has been marching with the people of west baltimore and has been giving television interviews around the 10:00 hour. and he said today whatever the decision that would be handed down by the state attorney he would trust it whether it was in favor of prosecuting the police officers or not in favor of prosecuting the police officers. he is a big fan of this state

attorney who he knows very well she is 35 years old, only recently elected. and he was making it clear whatever her decision he would be comfortable with it. so when the decision that did come down came down the decision to arrest and prosecute all six officers was made public people turned to elijah cummings, and he says history has turned a page today. >> did they see this man who was a mother's child? did they see this man who was just trying to get through life? did they see him as a human being? and i have come here today to thank god that marilyn mosby and her team saw him, saw him. the process has started. >> yes. >> that's the main thing. the process has started.

so many people in the neighbors that you have been filming, they had never seen a victory, and they had begun to believe that the system could not work for them so many of them have felt like the system had worked against them. and so again, we are beginning the process. >> reporter: congressman elijah cummings. within the past few minutes we heard from the mayor of baltimore, she said that nobody in baltimore was above the law, and asked the police commissioner to use the full weight and authority of his officer to make sure the six officers are now suspended from their jobs without pay while this plays out. she confirmed that five officers are as of this hour in custody. and she said whilst the vast majority of our policemen we know are good officers but for

those of you who wish to bring brutality, misconduct and racism to the job, there is no place in the work force for you. and the charges against the six officers are pretty wide ranging, from murder to manslaughter to assault, to misconduct. and it is worth making the point this doesn't mean they are guilty. they are innocent until proven guilty. and the police unit has said within the past few minutes that they are standing by the officers and they are calling on the state attorney to bring in a special prosecutor like we saw in ferguson. in that is something that she has immediateliry jektyiryyiry -- immediately rejected tony. >> we're taking look at live pictures probably over north avenue pennsylvania avenue that area. has there been a big public reaction to these developments?

>> reporter: well it's slightly difficult to say with great certainty. because i'm here at city hall where the media village is. the news conference given by the state attorney was right behind me. at the moment she talked about the medical examiner deciding it was homicide and there was probable cause to press charges, there was a huge cheer that went up. that was the first sign. since then people have been coming here and -- i think a lot of good nature argument have broken out. a lot of people have been arguing very close to the line of police officers and national guard forces which has now been reinforced. but i have just spoke to dwight pettitte who is a very very senior lawyer here. and he said what has happened here is that the issue regarding the arrest and treatment of

freddie gray has essentially gone away because the young people who have been protesting have got what they want which is freddie gray's day in court. he will effectively be in court when these officers come before a judge. but there are so many other issues which are affecting areas like west baltimore from a lack of jobs to a lack of proper housing, to many many other social and justice issues which extend far beyond this city and the protests that you see, and there's another one slated for this very plaza where i am tomorrow, will go on but they will now be tempered in terms of protesting about justice for freddie. >> john terrett for us. thank you. a new development today in the bridge gate scandal out of new jersey. a former top ally of new jersey governor chris christie has

pleaded guilty on conspiracy charges. and two other allies have been indicted. david shuster is here with more on this. david what happened in court today? >> what happened in court is this bridge gate scandal may have just derailed chris christie's presidential ambitions. his chief of staff was indicted on nine counts including conspiracy to exact political vengeance. according to the indictment these two, along with a federal witness, essentially who pled guilty and is providing information, there was this conspiracy to have retribution against the mayor of fort lee, new jersey who failed to support christie in his election and this was not only a big

inconvenience with the bridge lane closures but it violated criminal law. >> mr. whilesteen who was then the director of international capitol projects admitted in federal court this morning that he and others orchestrated a deliberate and illegal scheme to reduce the access lanes from 3 to 1 to punish the mayor of fort lee for not endorsing governor christie's election. >> it is alleged that governor christie was told that week about the scheme. and there was a telling moment from the u.s. prosecutor when he indicated that one of the reasons they brought charges is because bill bridget, and david all denied publicly and shortly thereafter that -- that there had been any sort of scheme. so the key question for governor christie it was alleged that he

was victimized by rogue aids and he was not part of this. does this investigation now lead to him. is david whilesteen now providing information to the prosecutors that would allege that governor christie has broken any laws himself? or can they get one of the others to flip and make the same accusation and this comes just a couple of weeks before chris christie is hoping to launch his presidential campaign. and this is not going to endear him to fund providers. he was in south carolina this morning. it was expected the announcement was going to come today. he made a little joke about developing news but there has been no direct reaction yet from him or his attorneys. >> terrific. david appreciate it.

are you talking to matt or am i? >> let's both talk to him. >> let's both talk to him. matt is on the line a reporter for pollicer new jersey. what is your reaction to what david is reporting? >> look he went to court today, and david whilesteen admitted yes, this is political retribution, which is something that we up to this point has pretty much been the narrative, but no one has really ever admitted to that so this solidifies that. that we know what this was. this was political retribution according to the person who pled guilty to two counts of conspiracy, and now it's drawing in and maybe not surprisingly because we have through documents that have surfaced drawing in two folks pretty close to governor christie. one who was a top official that christie appointed as a port authority and one who was a top

official in his administration. so it is not surprising but it is certainly coming at a time where governor christie is just around the corner and most likely announcing a presidential campaign. >> in the last 15 minutes i have been in the studio i have not been able to listen in to the news conference. do you know if the prosecutor took questions, and was the question asked and answers on whether christie is possibly going to be indicted or whether he had any knowledge. >> i know that press conference might still be going on. and what might be very important is paul fishman noted that nobody else is going -- he doesn't expect anybody else to be charged with the bridge-closure -- or with the bridge-closure scheme. so that kind of indicates that these other folks that we thought could be indicted other

players close to chris christie that kind of closes a door on them being involved in this at least. david sampson, close christie ally is being investigated for things that sort of -- kind of came to light because of the bridge gate investigation. so it doesn't close the door on future indictments to other charges, but as far as the lane closures go it sounds like paul fishman, the u.s. attorney sort of suggest the door on other indictments. >> mr. paul fishman is saying this is it no more indictments related to the lane closures it stops there, that would then go to chris christie's claim that he was victimized by rogue aids; that he did nothing wrong, and these other schemes that the u.s. attorney who you saw, the other schemes that he is investigating is there any

potential that any of these might catch up with governor christie? do you have a sense at this point? >> at this point it would just be speculation. but the attorney alan when david walked out of court, doubled down on comments he made quite sometime ago that evidence exists that criticizedtive could have been amare, or was aware, or was made aware of the traffic jams at some point. so more is going to be coming out from this. and he doubled down on those comments. so if alan left that cloud of uncertainty hovering out there, but as far as the lane closures themselves, you know he said that there won't be additional indictment indictments, but who knows what else comes from these investigations. >> you cover new jersey politics as much as anybody, and christie

is considering a presidential campaign. do you get the sense that governor christie walks away from this emboldened and now says i was right. i wasn't indicted and this is the end, everybody can move on. >> if you are a christie propoenent i think that's an extremely fair argument to make. we had a to ask him earlier in the week when news first surveys that whilesteen was going to plead guilty he said one it doesn't have to deal with me because i wasn't involved with this at all, and two it's not going to contradict anything i said during my two-hour-long press conference when he apologized that this was allowed to happen under his watch. so i wouldn't be the least bit surprised if he says something

if not today then in the near feature, that he says this goes along with what he previously said. >> and that's significant news if governor christie now has information that this is it christie can go out there and assure activists and donors that hey, this doesn't touch me. >> and yet there will be people who say this happened on your watch. >> and maybe even some republican rivals who will say you don't want that kind of politics in the white house. coming up next marking may day, workers around the globe spend this may 1st protesting and demanding better pay.

may day rallies are going on all around the world today to mark international worker's day.

in hong kong tens of thousands took part. and tens of thousands filled up red square today. and in cuba the president was joined by the venezuelan president, as a large crowd swarmed revolution square in havana. in seoul, some may day rallies took an ugly turn. officers equipped with riot gear used pepper spray to stop standoffs. harry fawcett has more. >> reporter: the union organizations behind today's events are protesting against what they see as an attempt to deregulate the government's attempt to weaken unions.

they say they want to see a near doubling of the minimum wage by the end of the year. this is far from the first big protest we have seen in cent weeks. there was a general strike of april 24th. there was a protest on the anniversary of the sewol ferry faster. harry fawcett in seoul south korea. may day rallies have also been charge in johannesberg south africa. >> reporter: i'm here in a stadium, and representatives of trade unions from across the country are gathering to celebrate labor day. the trade unions have played a pivotal role in the struggle against apartheid here.

they are making very well demands on the government. it wants wage increases for public sector workers. >> we demand 10%. we deliver the majority as staying away there their communities. and therefor the cost of living is too high in south africa. >> reporter: the government is saying if it were meet demands for a public sector wage increase it would cost them $1.7 billion next year and they don't have that money. the government of course is under huge pressure in this country, around 40% unemployed, over 50% of the country living in poverty, vast amounts of inequality and a huge disparity in welfare. and the union itself is suffering at the moment and there are questions as to whether that split could

compromise worker's rights in the months ahead. a group of scientists are saying the earth can be cooled by blocking out the sun. details next.

>> part of our month long look at working in america. "hard earned".

in the face of a rapidly changing climate, scientists are considering drastic measures to cool the earth. one is called geoengineering. as duarte geraldino reports for us now at least one major government is taking the idea very seriously. >> tornado crossing the road a quarter mile. >> reporter: global climate patterns are changing so much scientists are now considering a once taboo topic. geoengineering. some people call it planet hacking. literally altering the systems

of the globe. because of its cost and ease the first strike will likely be aimed at the sun. 16 top american scientists coauthored a paper entitled science intervention. while the paper does not constitute official u.s. policy it was requested and supported by key government agencies like the u.s. department of energy, nasa and the u.s. intelligence community, which includes agencies like the cia, fbi, and homeland security. in a statement the intelligence community tells al jazeera in part. it's interest in geoengineering is quote: >> with the solar geoengineering proposals the earth would start schooling in the next year. >> reporter: one of the secrets psych rowscopic particles that

might one day be used to shade the earth from the sun. if particles were injected into the sky, aerosols would spread around the world, partially blocking and reflecting sunlight. that's what happened naturally in 1991 when a volcano erupted. global temperatures dropped by almost a degree for more than a year. >> cooling the earth with solar geoengineering just requires a few people with a few billion dollars. >> reporter: yes, there are people who stand to lose but there are goes corporations even individuals who stand to gain therefore, not everyone's interests are aligned. the severe pain caused by global warming is likely to be felt in developing economies. >> i think the more likely

scenario is a scenario where any india or china or other tropical countries have massive crop failures due to heat stress and they feel we need to deploy some sort of solar engineering scheme to cool the planet quickly. >> reporter: but it would only cool the average temperatures. some countries could get even hotter. how about this singer ben e king has died. ♪ >> that was just one of the classics he recorded "stand by me." he was on the right there with james brown. and paul mccartney.
