the area looking for casings or other evidence. the officers conducted a search earlier today of the home of the two men, and it has not been disclosed what was found in that home. just before this cartoon contest was to end, these two was to end, these two [ technical difficulties ] >> bringing them down as they died here at the scene. now investigators say that this -- this is exactly what they had planned for and the security worked. >> they were there to shoot
people. we will continue to investigate. this is not going to be a real fast investigation. we have got our suspects. we continue to monitor social media, and other -- gather other intel, to make sure that we're not getting anymore -- or any threats. >> reporter: investigators have not said this is linked to a terrorist attack though they say they have not ruled possibility either. >> tell us more about the group and what they were trying to accomplish with this contest. >> reporter: well this group is called the american freedom defense initiative tony and they are based in new york city but they chose texas to host this cartoon contest, because this is the venue that hosted a pro-muslim community event that happened ten days after the
terrorist attacks in paris. the group's leader has said that this contest was about free speech. however, she has many critics, among them the southern poverty law center. >> heidi zhou castro appreciate it. thank you. katrina pierson is the spokeswoman for the tea party leadership fund. she was there last night, and told us what she saw. >> many of us were just winding down on the inside of the building. all of the speakers had spoken and we were getting ready to exit. but you could hear in the doorway people yelling shots fired. so we stopped and looked at each other, and immediately the police department came in sealed off the exits and let us know we needed to stay in the room because there was an active shooter on the scene.
they wanted to move us to a more location within the building because they had thought that they had seen explosives on one of the suspects. so when they moved us into the auditorium, the center it was interesting, because a woman had an american flag in her purse, and when she held it up everyone immediately started singing god bless america, following that were chants for usa, and immediately following that, everyone began to pray for the officer shot, the police department keeping us safe. >> pierce credits the garland police department with preventing even more violence. president obama says he will continue to work on issues of equality and education even after he leaves the white house. he spoke at an organization to carry out the work of my brother's keeper initiative. he says a sense of unfairness
among minorities has fuelled the recent protests. >> reporter: this is personal says president obama, and some communities he says simply have the odds stacked against them. he says the life chances for young people living in many of these impoverished communities around the country are simply not what they are for their peers in other groups. the president you are right was in the bronx talking about my brother's keeper an initial le started early in 2014, after the killing of trayvon martin and the ensuing controversy. he is now trying to ensure his legacy forming a structure that can carry on after he leaves office early in 2017. the idea is to mentor at-risk
youth for many of these communities, communities that the president says where young people live and what we calls a opportunity gap. >> too young men and women feel like no matter how hard they try, they may never achieve their dreams. and that sense of unfairness -- unfairness -- unfairness -- [ technical difficulties ] >> of people not hearing their voices that's helped fuel some of the protests we have seen in places like baltimore, ferguson, and right here in new york. >> reporter: tony a study from harvard reported in the "new york times" say among the nation's 100 largest counties and jurisdictions, the one where children face the greatest odd of facing controversial, baltimore, maryland. >> wow, my hometown. will the president get support
from congress? >> it's unlikely he will get more money. conservative media today pointing out in the president's stimulus in the outset of his administration in 2009 some $1.8 billion was targeted towards baltimore. paul ryan of course the former participatal candidate on the ticket last time around today he is quoting as saying the social policy -- the old-fashioned social policy back from the 60s clearly doesn't work. he is laying it at the feet of many democratic social programs, and talking about further well form reform. so sort of an idealogical retrenching here on both sides in the wake of the unrest in baltimore and other mayor american cities. >> mike thank you.
i want to bring in the president and ceo of every green health, and he wrote a pretty powerful op-ed in today's baltimore sun on how the city can move forward and a long time friend. good to see you. >> good to see you, tony. >> as a long time baltimorean, when you watched the rioting last week it must be said in the lack of real answers in the fred freddie gray case at the time, what did you see? he time, what did you see?
>> [ technical difficulties ] >> so i'm taking you governor. >> i appreciate that. [ laughter ] >> and you want to get to the root of the problem, some of the systemic problems of inequality in baltimore. you wrote about it today. where do you stand? >> first of all it has to be comprehensive. baltimore has a choice right now. a choice to let things go back to normal and frankly things are going back to normal in quotes, but for many in baltimore, that is not adequate and we have got to try to deal with this, before we have growing disparities and inequities in this city. we need to make the choice to address this comprehensively. it doesn't necessarily require more money. four-legged stool, a stool needs four legs to stand properly and
for a community to be successful and healthy at large, you need affordable housing in safe neighborhoods, you need decent public schools, you need health care and livable wage jobs accessible to adults in that community. the communities that were affected by the riots, as you well know, tony have none of those four legs of the stool. and we have got to provide all of them. and in order to do that you don't necessarily need lots more money, but what you do need is the political will to do that and frankly, i haven't seen it here. >> let me push you on the money aspect of this. i wonder is there enough of a tax base left in baltimore to do what you want to do? look you know this the '80s and '90s saw a lot of money and
a great of great jobs but steel is essentially no more. the auto business has taken a real hit, the port business has taken a real hit. it there money, a tax base jobs to do what you want to do? >> very good point. we're one of very few cities that are our own county. there are very few that are that situation. l.a. city is 3 million people, but part of a 10-city county. baltimore has most of the non-profits in the city so we don't generate the income tax that most jurisdictions do. i have argued that we need a regional approach in order to correctly address this and that's true in other cities as well but even more importantly here in baltimore. >> one more point on education.
the president says education is the key. and i know you believe that. why do so many minority kids -- and in particular black boys don't read at grade level. everyone i have talked to, so many smart people there in that city and state. tell me repeatedly if you can get these young boys reading at grade level, that is the difference maker. that's the thing that will transform their lives. >> it's crucial, and >> it's crucial, and
[ technical difficulties ] >> there were reports of a police-involved shooting where riots broke out after the funeral yesterday. a man carrying a gun was arrested. lisa stark was in baltimore. lisa, give it to us straight because a lot of people got it wrong. >> reporter: they absolutely did. it was right in this neighborhood and it happened earlier today. as you said some very tense moments. apparently began when police saw
a man on a security camera that appeared to have a gun. they tried to arrest him. he ran, and then a shot rang out. on social media, reports started coming out that police had shot this gentlemen. it turned out not to be the case but crowds started gathering, and there was a huge police presence as well. police tried to quickly put out the word that we did not fire any shots, and they made it clear that the man they did arrest on a weapons charge the man was not injured at all. here is the lieutenant colonel. >> he was checked out thoroughly by the paramedics. he had no injuries on his body whatsoever. he did not want to go, but they took him anyway. >> reporter: now as he indicated there, the gentlemen was not injured. he didn't want to go with the
ambulance, but they did take him to the hospital as a precaution. quite a contrast to what happened to freddie gray who pleaded for medical help. it appears this man's gun may have gone off accidently, tony, and that was the shot. >> gotcha, all right. [ technical difficulties ] >> baltimore is trying to recover from the unrest following freddie gray's death, how is the city trying to move forward now that the curfew has been lifted? >> reporter: right. the curfew is off, as -- as you indicated. also the national guard, 3,000 strong as well as a thousand from the state of maryland and surrounding states are now starting to pull out --
[ technical difficulties ] >> and also earlier today, the two senators from maryland held a round table here in the community with community leaders and the clergy and the point they were trying to talk about is how do we move forward now? how do we move baltimore forward in so many of the areas that it needs, so that process has now begun, hoping that some progress can be made. tony? >> all right. lisa good to see you, thank you. a new york city police officer shot in the head this past weekend has died from his injuries. he was shot on saturday while trying to stop a man suspected of carrying a handgun. he is the third new york city police officer to be killed in the past six months. the suspected shooter was arrested and is being held without bond. . in israel the recent police beating of an ethiopian police

israelis part of the wider movement drawn from spain, portugal the middle east and africa. a significant number of these israelis were actually born in this country, and they insist that they have lived as marginalized citizens since birth. few taking part were willing to be interviewed, fearing further victimization. but one former member of parliament outlined the reason for the protests. >> we're here to say enough is enough, because we see more and more attacking by the police. not just the police but treating us like criminals. and because of the difference of culture, they are attacking some youngest early. >> reporter: and another demonstrator identified only by the name david explained why he was there. >> translator: it's tough. i don't know what is going to happen. i myself am a police officer,
and i took my uniform off to demonstrate. that says something. it's very difficult. >> reporter: the demonstration that had begun so peacefully degenerated into violence. more than 50 police officers were injured, as well as a large number of demonstrators, yet it was significant that despite what appeared to be explosive violence there were no serious injuries. >> that is due to the fact of them using only water cannons to disburse the crowd, and stun grenades only make noise and scare off the rioters, but causes no damage whatsoever. >> reporter: the center of tel-aviv is being cleaned up but little will wash away the shock of the violence. add two more for the field of 2016, a computer executive, and former neuro surgeon both

evening about the oldest survivor of nepal's earthquake. the 101-year-old man was buried under the rubble of his own home. faiz jamil spoke to the man as he recovered in a hospital. >> reporter: at 101 years old, he is the oldest survivor of the earthquake. he was at home when the ground began to shake. >> translator: the walls around me collapsed. the ceiling came down too. i was trapped inside. i received injuries to my foot hah my arm. >> reporter: he was alive during the last major earthquake in 1934 but says this one was much worse. >> translator: everyone in my family was alive, there were just two of us there, but seven other people died in our village. >> reporter: he is bothered by all of the attention he is receiving, but it's a story that has sparked hope.

under the influence of an evil older brother. one relative said he had a rage inside of him. the defense said in 2012, tamerlan went to train with fighters. one usin testified: >> i think it falls into the defense strategy of showing that the older brother was in control, and the younger brother was kind of going along, really not the one making the decisions, not the major instigator of what happened. it only takes one juror to vote for a non-death penalty resolution, and then he gets life in prisonment. >> reporter: after testimony concluded for the tsarnaev relatives, court took a short
break, and we saw tsarnaev show another act of affection, blowing a kiss to his crying cousin. doneny. >> erika, how did the prosecution push back on the family's testimony? >> reporter: you know, they actually only cross-examined two of the five relatives. and in one of the cross-examinations the prosecutor said just to be clear, none of you have seen dzhokher since he was a small boy, because he left, you know, when he was only eight years old. and yes, none of them had seen him since. so they were trying to make that point. again, federal government maintaining he was absolutely an equal and coconspirator alongside his brother to execute these deadly attacks. >> erika, thank you. in france lawmakers are set to vote on a proposed surveillance law which would require internet

and commentary about it but we have never had a modern western country befault on a debt and we have never had a country that is part of the euro zone default. people could experience some short-term pain if markets do panic. unclear what will happen. the hope is a deal gets struck before finance ministers meet in brussels one week from today. the next week, tuesday is when that check has to be cut. time is running out, and that could mean more drastic measures like greece restricting the free flow of money. people will want to get their money out of greece. unclear what is go to happen. >> what else are you working on tonight? >> we're looking at what people with virtually no chance of

probation when the acts were committed. this sentence is necessary to deter others. it is necessary to protect the public from harm. >> reporter: and tony the courtroom was very quiet as the ruling was being read. he dropped his head down to the table as he heard it. this was the first juvenile resentencing case to be reviewed here. prosecutors issued a statement saying based upon the heinous nature of this crime, and the fact that davis was a willing participant in these murders, we believe the sentence was appreciate. >> several of davis' family members were in the court today. what was their reaction? >> reporter: as i mentioned it was very very quiet in the courtroom. and the judge was speaking at a very low volume everybody was leaning in to listen in to what
she was saying. so as we got up a lot of the family members didn't hear. they were asking but once they figured out he was being resentenced to life in prison they were very disappointed. and one relative member said it was disbelief and sadness, and she believed the judge had made up her mind before the proceedings. >> we believe she disregarded all of the witnesses and support and mitigation as uncompelling biased and misinformed, and we'll continue to fight. he has spent 24 years in prison and is not the same person that he was at 14 years old. >> i'm angry, i'm more concerned about his whereabouts now, and we're going for the appeal. i know it will take some time for the appeal but i think she
pretty much had her mind made up but i think he really deserves a second chance. >> davis's attorneys maintain that he is a changed person. they say while he is disappointed by today's decision they will determined to fight. they plan to file an appeal and this is just the first of dozens of potential cases here in illinois where juveniles were sentenced to mandatory life sentences that we expect to go to the system coming up. >> usher thank you. for a look at what is doing up at the top of the hour john siegenthaler is here. coming up the attack in texas, what police say about the alleged gunmen and the person being hind the cartoon contest of the prophet muhammad. and with a crowded field of g.o.p. hopefuls we'll take a look at the money they have to spend to get national recognition, and how that run could shape their lives in
