With scott pelley. Pelley we begin tonight with two Police Shootings in two cities, charlotte and tulsa, and two black men dead. The shooting of Keith Lamont Scott in charlotte yesterday sparked a night of violence. Police say it all started when officers went to arrest another man and encouldered encountered scott instead. What happened next is in dispute, but the African AmericanPlainclothes Police officer who shot scott is on paid administrative leave while an investigation is under way. David begnaud is in charlotte. Reporter this video shot by a resident shows 43yearold Keith Lamont Scott on the ground after being shot by a Police Officer. It is the only visible evidence the public has seen. The shooting led to anger and overnight clashes between residents and Law Enforcement with rocks, bottles and tear gas flying. A life was taken. Reporter 24 hours after the shooting, and there are dueling narrativesve what happened. An officer claims he saw scott inside of his vehicle with a gun. As the officer approached, police say scott got out of his car with the gun and refused to drop it when ordered. Police chief kerr putney. He stepped out, posing a threat to the officers, and officer Brentley Vinson subsequently fired his weapon, striking the subject. Reporter vinson, who has been on the force for two years, was not wearing a body camera, and while there is body and dash cam video from other officers. Oh, my god. Reporter . The Police Department has not released it. I dont know whats going on. Reporter witnesses like tanicia williams saw it differently. She says scott, married father of seven, was doing something he did every day, reading a book in his car, waiting for his son to get off the school bus. Did he have a gun . No, he did not. He had his hands up. His book fell off his lap. He walked to the back of the car and they shot him four times. A weapon was seized, handgun. I can also tell you we did not find a book. Reporter tensions in this community were already high after an unarmed black teen was shot this august by a white neighbor as well as lingering anger over the mistrial of a white Police Officer in the death of an unarmed black man three years ago. The mayor of charlotte is asking people to stay calm. She says she wants that video, the dash cam footage, the body camera video, all of it to be released publicly as soon as possible. Scott, you may be able to hear the helicopter hovering above me. Right now theyre tracking protesters who are on the march again tonight. The police chief says hes bracing for what could be another long evening. Pelley David Begnaud if charlotte for us. David, thank you. Well, the Justice Department tonight is assessing the charlotte shooting, but it has not opened a formal investigation. It is investigating the friday night Police Shooting of Terence Crutcher in tulsa, oklahoma. Manuel bojorquez is there. We know he was unarmed. Yes. We know he was moving slow. We knew he didnt commit a crime, like the new york bomber did, who is still alive. Yeah. Reporter in new york today, Terence Crutchers twin sister tiffany repeated a call for charges against the officer who shot and killed her brother friday. He wont show me his hands. Reporter police say crutcher did not obey commands after they responded to a call of an abandoned s. U. V. Hes got his hands up there for her now. Reporter at one point footage from a Police Helicopter and dash cam shows crutcher walking away from officers with his hands up. When he reached the drivers side door, one officer tased him. Then officer betty shelby fired her gun. Shots fired Reporter Police confirmed crutcher, a father of four, did not have a weapon. A source tells cbs news officers found a vile of the hallucinogenic drug pcp in the s. U. V. Crutchers family calls that a distraction. This is a nonviolent protest. Reporter protests have happened here almost daily, but unlike charlotte, they have been peaceful. The may were believes releasing the videos made a difference. We saw what had happened first in other places, where people tried to gloss it over, put a good spin on it. We didnt this that. We wont do that. We wanted to be transparent. Reporter officer shelby is on paid leave during the investigation. Scott, tulsa police explained today that although they received funding for body cameras in july, rolling them out takes time. Theyll Start Testing them on 40 officers next month. Pelley manuel bojorquez, thanks. Well, its video thats leading the f. B. I. Tonight to ask for help identifying these two men. They are wanted for questioning as possible witnesses in the weekend bomb blasts in new york and new jersey. The man charged in those attacks is recovering from gunshot wounds. Homeland security correspondent jeff pegues is following this. [explosion] reporter at 8 30 saturday night, a Pressure Cooker bomb exploded on west 23rd street in manhattan. The f. B. I. Is appealing for help in finding these two men who were four Boston Celtics away on west 27th four blocks away on west 27th street at the same time. Police say the two men removed a bomb from the piece of luggage, putting it on the sidewalk, and then walked away, leaving the device but taking the suitcase. The bomb never exploded. N. Y. P. D. Counterterrorism chief james water. They are witnesses. There are no criminal charges. Theyre not in any jeopardy of being arrested. So if you can help us find them or anybody else can Tell White House they russia we would be very interested to speak to them. Reporter investigators are still unsure if Ahmad Khan Rahami was part of a cell or acting on his own or if there are still other bombs unaccounted for. Rahami bought the ingredients for the obamas on ebay, including chemicals, ball bearings and electric igniters. The f. B. I. Is still trying the figure out where he built the bomb, but two days before the bombings, the documents say a Family Member film rahami burying a small black object in his backyard. A fuse was lit, there was a loud noise and flames followed by billowing smoke and laughter. Today at a counterterrorism hearing in washington, Homeland SecurityCommittee ChairmanMichael Mccaul held up a copy of rahamis handwritten journal. He talks about god willing the sound of bombs will be heard in the streets, gunshots to your police, death to your precious. Reporter blood stained with a bullet hole through it, rahami wrote about martyrdom, and his praise of militants suggests he took inspiration from al qaeda as well as isis. Investigators are still trying to figure out how rahami was radicalized and by whom. Scott, a u. S. Government source says rahamis wife was in dubai when she spoke with f. B. I. Voluntarily. Pelley jeff pegues, thanks very much. The f. B. I. Investigated rahami two years ago, but he was not considered a threat at the time. Its not first time someone ainvestigated by investigators has later been accused of terrorism. We asked anna werner to look into this. Reporter as Ahmad Khan Rahamis case moves forward, federal agencies are working to keep up with what former f. B. I. Agent manny gomez calls a tsunami of potential threats. Do you think people are being mised . Absolutely. The f. B. I. Does not have the resource, both legally and in terms of manpower and funding. These people are being radicalized quicker than we could identify them. Reporter in rahamis case, despite his father calling him a terrorist in 2014, in his yearlong stay in pakistan, and f. B. I. Source says at the time it found nothing in its indicators, such as links to other known terrorists or radicalized behavior to, point to rahami being a terror threat. Since 9 11, the Homeland SecurityCommittee Says there have been at least 166 homegrown jihadist plots in the u. S. , including attempts to join terrorist groups overseas and execute attacks at home, an average of 11 per year. Just this year alone, 26 people in the u. S. Have been arrested in 13 states for isisrelated activities including plots to attack, Financial Support and weapons charges. Sometime there are clues, but to make a case, authorities need evidence that they often do in the find. The orlando pulse nightclub shooter, omar mateen, had been on the f. B. I. s terrorist watch list for ten months and was investigated by later removed from the list. In june he killed 49 people. Cbs news consultant Fran Townsend says the system needs improvement. You want the terrorist watch list to be overinclusive, so if there is somebody you think may be but you dont have enough, you want it to alert other agencies to put more information in that might push you over the edge. Reporter since 2014, authorities have arrested 105 people in the u. S. Scott, they say those people were plotting attacks, attempted to join isis, or provided money, equipment or weapons to that terror group. Pelley anna werner, thanks. Today leaders of congress dropped their gavels and grabbed a hammer to pound in the first nail on the platform for the inauguration of the next president on january 20th. Today donald trump drove home his pilot with African American voters, and heres Major Garrett. Reporter donald trump met with handful of sympathetic black pastors in cleveland today. God, i ask that you would touch this man, donald j. Trump. Reporter trump was introduced and partly overshadowed by former boxing promotor don king, who used a racial epithet while describing discrimination against African Americans. If you are dancing and sliding and glideing [bleeped] i mean negro, you are a dancing and sliding and gliding negro, so dare not alienate because you cannot assimilate. So, you know, you going to be a negro until you die. Reporter the effect was unsettling and symptomatic of trumps pitch to African Americans, one hes made largely to white audiences. Trump has turned down speaking invitations from the naacp and other civil rights groups. Yesterday in north carolina, trump said this about the state of black life in america. Our African American communities are absolutely in the worst shape that theyve ever been in before, ever, ever, ever. Reporter we asked toledo pastor kay David Johnson how trump can better reach out. Is trump a credible republican nominee to speak to the African American community . He has not sewn seeds and nurtured those seeds in the African American community. There is no closeness, there is no trust that has been developed. Reporter trump today called for nationwide use of stopandfrisk tactics to reduce crime. Scott, those policies were discontinued in new york city after they were ruled unconstitutional because the vast majority of those stopped and frisked by police were minorities. Pelley Major Garrett on the campaign for us tonight. Major, thank you. Today Hillary Clinton urged Union Workers to stage an intervention for friends considering voting for trump. She pledged to build an economy that welcomes handicapped workers and promised to end the subminimum wage for the disabled. Shes campaigning in florida, a mustwin for trump, where the candidates are now tied. Be sure to tune in here on monday evening for the first president ial debate, clinton versus trump, 9 00 eastern on cbs. At the u. N. Today, secretary of state john kerry tried to resurrect the syrian ceasefire, asking all sides to keep their warplanes away from deliveries of food and medicine. The truce shattered monday after a week when an aid convoy was destroyed near helpo. 20 civilians were killed and the u. S. Blames russia. Elizabeth palmer reports tonight from syria. Reporter as the pentagon continued to insist only the russians had a warplane directly over the bombed aid convoy, the syrian army carried on shelling the rebelheld side of aleppo. Its been relentless, and some on that side decided they just couldnt take it anymore. When our group reached the crossing point, amir told us, we came under fire and had to scat. Amir is too afraid to show his face, but he was one of the ones who three nights ago made a run for it. There are ways out of rebelheld aleppo for people who want to come to the government side. One of them is right through this gap, but every journey like that is a dangerous gamble. We climbed up to the second story in a nearby building to see the lay of the land. Are there sniper positions in those buildings we can see . Out there is nomansland in this divided city. I managed to cross it, said amir, but my family didnt make it. When the shooting started, he told us they turned back, but he pressed on and now finds himself alone on the government side of aleppo, facing an uncertain future in a borrowed room right on the front lines. True, there is no bombing here, but theres scant opportunity either and very little hope. There was so hope, scott, when the ceasefire was in effect that violence would fall and aid would begin to flow more freely, not only in aleppo but across syria. Even that hope has now been crushed. Pelley Elizabeth Palmer continuing her reporting from inside syria. Liz, thank you. Coming up next on the cbs evening news, congress sticks it to the maker of the epipen.

You put it out of reach of the average consumer. Reporter mylan c. E. O. Heather bresch faced backlash for her companys pricing and revenue strategy. I wish we had better anticipated the magnitude and acceleration of the rising Financial Issues for a growing minority of patients. You never anticipated it . You raised the price. What did you think was going to happen . Reporter since 2009, the price of epipens has slowly increased from about 100 for a two pack to more than 600. The 47yearold tried defending the spike by saying the company only makes 100 for every two pack after cost. Committee chairman republican jason chafus. When the juice is 1 and youre selling it for 600, theres room for profit. Reporter mylan has been the focus of public scrutiny since families complained about skyrocketing costs. In response to criticism, the company increased the value of coupons to families and has announced a 300 generic version of the drug. For lexi hennigers family, their 1,200 pharmacy bill for two kids was cut in half. It wasnt quite what we were looking for from the company. We were hoping they would lower the overall price. Reporter lawmakers on both sides of the aisle agreed. Democratic congressman elijah cummings. Im concerned that this is a ropeadope strategy. After mylan takes our punches, theyll fly back to their mansions in their private jets and laugh all the way to the bank. Reporter an f. D. A. Official also testified during the hearing.
