The arrest coming just as a Prayer Service being held for the five victims. Abcs Neal Karlinsky is right there in burlington, washington with the latest this morning. Good morning to you. Reporter thats right, they were able to zero in on the suspect through tips and surveillance cameras here in the mall parking lot, able to identify his car and track it to a nearby town where they found him not hiding out, but simply walking around. The arrest happened without a single shot fired. Right there walking. Undetained. Reporter suspected cascade mall shooter, arcan cetin, a recent High School Graduate and grocery bagger. According to his facebook page. Northbound on the sidewalk and i instantly recognized, did an abrupt uturn, pulled my gun and took the individual into custody. They found him in a community 40 minutes away from the shooting. Reporter officers spotted him simply walking down the street. He said nothing. He was kind of zombielike. He did not have a weapon with him. He had a leather satchel. Appeared to be a computer inside the bag. Reporter Police Arrested cetin almost 24 hours after the shooting rampage inside this macys. Four women and one man shot to death. Near the makeup department. A my space of him posing with various firearms. Hours earlier, police had released new images from inside the mall. Cetin they say in a tshirt and shorts, no tactical gear, and nothing to make him stand out before allegedly opening fire. Three to four down inside. Ive got one rifle left in this area. To see it happen 20 feet away from you is just its insane to me. And i never thought that i would be in that position to be staring at somebody who was losing their life and i cant do anything about it. Reporter the victims range in age from a teenage cancer survivor to a senior citizen. Police are looking into reports, cetins exgirlfriend may have worked at the macys, but for now, the motive remains unknown. The suspect is from turkey but a legal resident of the united states. Theres no believed link to terrorism at this point, and the suspect will make his First Court Appearance on monday. Paula. That motive, the big question. Thank you. The other big story, the ongoing unrest in charlotte. Bowing to pressure, the Police Department releasing two videos of the Fatal Shooting of Keith Lamont Scott after days of protests demanding that the footage be made public. Our eva pilgrim has been in charlotte all week. Theres a lot these videos show reporter paula, the Peaceful Protesters overnight saying, this is not enough. They want the full video released. They have been caulk for it since this shooting happened last week. Meanwhile, the city of charlotte ramping up security for todays panthers game declaring it an extraordinary event prepared for more protests now that this portion of the video is out. This morning, a first look at the police video showing the Fatal Shooting of Keith Lamont Scott. Scott get out of his suv, walking backwards, hands by his side. When four shots are fired. We got shots fired. One suspect down. It does not make sense to us how it was possible that this incident resulted in the loss of life. Reporter the body cam video showing a different angle. A uniformed officer using a baton trying to break the passenger window to get scott out of his suv. Scott is seen standing outside father of seven, lying on the ground. Police running up with guns drawn. From his hand. Reporter officers checking his pulse begin to administer aid. We need to hold the wound. Reporter police also releasrele releasing pictures of the evidence taken from the scene, saying scotts dna and fingerprints were found on the loaded gun they recovered. Theres no single piece of evidence that proves all the complexities involved in this investigative process. What i see on the video is the failure of the police to use all of the resources that they had at their disposal to avoid killing keith. Reporter family members say 43yearold keith scott was just sitting in his suv waiting to pick up his son from school. According to Police Officers were in the neighborhood for an unrelated arrest warrant. They saw scott with marijuana do those actions, do those precious seconds justify this shooting . What we know and what you should know about him is that he was an american citizen who deserved better. Reporter the police chief saying they will release the rest of the video when this investigation is complete. Dan. Eva pilgrim, thank you. Lets break down ts consultant brad garrett formerly with the fbi. Brad, good morning. Two things strike me from this new video. First, its really not clear that Keith Lamont Scott is holding a gun and second, his arms are at his side in the moment he was shot as far as i can tell and hes backing up. So do you see what im seeing here . Im seeing the same thing, dan. So it raises the following questions. He steps out of the vehicle as he moves backward, does his arms you hear the cops yell, drop the gun. Drop the gun. He apparently doesnt drop the gun. At some point from their Vantage Point he must have raised the gun. Because i cant think of any other justification to shoot him. Right. Is there some other tactic they could have used in that moment like tasing him or letting him continue to back up . Either one is a possibility. And it also raises the bigger question is why did you just not leave him in the vehicle and sort of wait him out . The other thing we see on the earlier videos is the gun on the ground after scott has been shot and some people have pointed out that the gun seems awfully far away from him. Does that raise any suspicions for you . No, because typically, you move a gun away from somebody that you have just shot or arrested for the obvious reason so they cant reach for it if they are still conscious. Thank you very much. So many questions still. We appreciate you helping us clarify to the extent possible. Thanks again. Just the beginning of those thanks dan. In politics a Huge Development just one day before the highly anticipated president ial debate. This race, it is tighter than ever. Thats according to a new abc News Washington post poll that shows the candidates are just two Percentage Points apart. Hillary clinton has 46. Donald trump has 44. Heres a look inside the debate hall at new york where Hillary Clinton and donald trump will spar in their first of three president ial debates. Abcs cecilia vega joining us in studio with more, on what we can expect. Thats the big question. Good morning to you. I think we can expect fireworks. Good morning to you. The super bowl of american politics just a day away and it is expected to draw a super bowl sized audience. 100 million americans likely to watch this showdown. But this morning, all eyes on two people who might be watching from the front row right inside that debate hall. Im going to fight. Reporter tminus one day to couldnt be any higher, and the invite list couldnt be any wei weirder after Hillary Clintons team offered a ticket to one of the best seats in the house to Donald Trumps reality tv billionaire nemesis mark cuban. Ill give you 25 grand for 33 . Just say yes. Reporter trump took to twitter threatening to offer an invitation of his own saying if dopey mark cuban wants to sit in the front row perhaps i will put Gennifer Flowers right alongside of him. Gennifer flowers being the woman who had an affair wi she reportedly told the new york times, yes, i will be there. The Trump Campaign would not say whether an actual invitation was extended. We are going to show the whole world that america is back. Reporter trump attending a rally in virginia, take a break from debate preps where hes not holding mock debates but question and answer sessions rudy giuliani. Some aides concerned trump hasnt spent enough time practicing, and gets easily distracted. Clinton deep in briefing books and mock debates, her team finally revealing a tightly guarded debate prep secret. The person picked to play her opponent, a long time aide known for being shrewd and combative felipe reigns. Okay. So gennifer the audience tomorrow night, while clintons camp says Hillary Clinton plans on using the debate to discuss issues that make a difference in peoples lives. Its not surprising donald trump has chosen a different path. I know you want to come with me. But im sorry. I dont get any tickets. Are you sure you dont have an extra ticket . Yeah. Ill hide in your luggage. Theres so much intrigue about who will be there in the audience, but both parties feel like theyre going into this particular debate with an unfair disadvantage. How are they trying to gain the rev rev reves refs right now, and he has already called the system rigged, and going after the debate moderators talking about which parties they may or may not vote for. Hillary clinton is complaining about the moderators, too, saying she doesnt feel like shell get fair questions, he will not have difficult questions like her because the bar is lower for him. I think what well see is big fireworks on that stage. Do you think george might be able to hook me up with a ticket . Ask him. George. Good luck with that. Thank you. For more on that lets bring in George Stephanopoulos who is going to be hosting this week later this morning. Let me ask you about what kind of impact do you think in the end a debate like this is going to have . Our poll shows 74 of americans say theyre going to watch, but 80 say they dont think its going to change their mind. There are big debates about debates. And how much difference they really make. Most people believe that have watched for a long time, believe that generally the debates dont make a big different. In these final weeks. Tend to reenforce the trends inside the race. Heres why this year may be different. Number one, the size of the audience. Maybe more. The biggest debate audience ever. Number two, voters are unusually fluid this year. Usually by this time in the race the number of undecided voters is 5 to 7 . This year it could be double and theyre going to be watching to see how they do. Its mindboggling to think people havent made up their mind. We have been digging into this poll that shows its tighter than ever. We want to talk about the candidates and their challenges. Particularly donald trump, 6 untrustworthy, temperamentally unsuited and insufficiently knowledgeable to serve as president. Can he use this debate . Those numbers have been coming down. He has been making progress over the last month. His job tomorrow night is to appear calm, in command and he knows what hes doing, knows what hes talking about. Well see whether Hillary Clinton will call him out on that. Remember in past debates donald trump is usually one of 10, 11, 12 people on stage. Never one on one for 90 minutes time with policies that hold up. A whole new dynamic for him and for clinton, really, its all about her honesty and her health. Only 36 see her as honest and trustworthy and after that recent bought with pneumonia 53 think shes in good health to serve as president. Can she made it on either of these issues . Safe to say she cant afford one of those coughing fits on the stage. Other than that i dont think the health is going to matter. Its this issue of trustworthiness, her biggest hurdle no question about that, can she find a way in this debate to handle that liability to appear authentic, to appear a little more warm, but also in command and put the debate to donald trump . I have to say, im just plain looking forward to this thing. A combination of breaking news, the super bowl and the Series Finale of downton abbey. Were going to talk to the campaign managers. About the debates. I would be shocked if the commission on president ial debates lets Gennifer Flowers this would take it definitely further into the reality tv zone. Thank you very much, george. Appreciate it. I want to remind everybody, hes got a big show coming up later on this week. On the eve of the debate. He is as he said going one on one with Clinton Campaign manager and Trump Campaign manager, plus libertarian president ial nominee gary johnson. And tomorrow night george will be leading our debate coverage joined by martha raddatz, david muir, raddatz, david muir, tom llamas, cecilia vega, matthew dowd and Cokie Roberts.
