Tonight the mother of that Police Officer who shot and killed an unarmed man in the back is being out for the first time. After a son became one of the most talkedabout people in america. This as the witness who filmed the disturbing video comes forward with new details about what he says really happened those minutes that changed so many lives. Reporter tonight, newly released dash cam video shows the moments before the tragic shooting of walter scott, first seen here in cell phone video now making headlines around the world. The gunfire was not captured on the dash cam. Instead, we see a standard traffic stop. Officer Michael Slager pulls over scotts black mercedes for broken taillight. License, registration and insurance card. Reporter scott tells the officer he doesnt have a registration card or insurance. All right, be back with you. Reporter officer slager walks back to his patrol car. Moments later scott gets out of the drivers seat. Stay in the car reporter 18 seconds later, routine gives way to man on the run. And soon scott, an unarmed father of four, is shot dead. The officer now arrested and charged with murder. Tonight two mothers are grieving. Judy scott, scotts mother. I pray that this never happens to another person. This has got to stop. Reporter and slagers mother karen sharp. I want her to know that this is also hard for me. And i would never, ever want there i would never have wanted this to happen to their family, her. Reporter speaking out for the first time she tells my colleague, Steve Osunsami she cant bring herself to watch the video that shows her son killing an unarmed black man. Ive purposely not watched it. Ive purposely not tried to hear peoples comments about it. I dont i i just cant watch it. I cant read the papers. I just cant. Maybe to some people thats oh youre being in denial. But im sorry, i just cant. Reporter she says slager is not a racist, hes a loving son, a father to be. I want everybody to know hes a very good person. Hes not a hes not a hater. Hes a very good person. Hes a hes a sweet, sweet kid. Hes my kid. Hes my child. Reporter a sharp contrast to the man seen in this cell phone clip, firing eight rounds at scott. Disturbing, graphic images captured by santana, 23yearold dominicanborn barber who was on his way to work. Today he shared new details about what he witnessed that saturday morning. What drew your attention . Well the chasing of the police, the officer. The Police Officer chasing yeah to mr. Scott. I saw him running. I didnt know what was going on. Maybe five seconds later i saw the cop after him. Reporter santana said he started recording just after officer slager fired his taser. Trying to get away from the taser. Reporter he contradicts the claim scott tried to grab the stun gun. Did you ever see mr. Scott take the taser away from the Police Officer . Ever have control of the taser . No, no that never happened. Reporter in the video, after scott goes down slager appears to drop an object near his body. On the video you see officer slager at one point walk back and pick up something off the ground. Did you notice that . Yes, i noticed. What was it . I cant say it was a taser, but i dont know. Reporter following the shooting police wrote in an incident report they continued to perform first aid and cpr until e. M. S. Arrived. Santana says from what he saw, thats just not true. Did you see anyone perform cpr . I didnt see any cpr. Breathe into his mouth . No. Compress his chest . No. Try to revive him . Nothing like that. Reporter santana says he waited a few minutes before telling slager and another officer at the scene he had recorded everything on his cell phone. Did he attempt to say anything to you, look at you . He look at me. Reporter he says the officers asked him to wait at the scene but he left. I just got away from there. You walked away . Yeah. No one followed you . No. An officer, hey, come back let me talk with you . No. Reporter within days hed make the video public prompting police to charge slager with murder and reexamine his old cases and complaints. In mr. Scotts case we only have video and a dead witness. But today we have a live witness. Reporter in one account, 33yearold mario gibbon in a press conference today, detailed how in 2013 slager tased him in the stomach with a stun gun even though he had his hands up. He said hes planning to sue. What came to my mind yeah if he even tried to listen to me or investigated hed probably be alive because he wouldnt have been an officer in the field. Reporter he was mistaken for a burglary suspect. All charges against him were eventually dropped and investigators cleared officer slalger of any wrongdoing. Slager used a taser in that case. In the last five years police in South Carolina have fired their guns more than 200 times and in every case they were cleared. No charges. Until now. Tonight the South CarolinaLaw Enforcement division released a statement saying the cell phone video confirmed their early suspicions. There were inconsistencies. We believed early on there was something not right about what happened in that encounter. If convicted slager could face the death penalty. Santanas cell phone video may be the most compelling evidence against him. But it almost didnt see the light of day. I thought about erasing the video. Why . Because it was dangerous. Dangerous to keep that information on me. Because you were concerned for your own safety . Yeah. To expose his identity to Police Officers who are supposed to protect the community, but who he watched execute a man and tell lies about what they had done afterwards, it was dangerous for him. Living in that community. Hes got to watch his back. Reporter slager has yet to enter a plea and his new Attorney Says its too soon to issue a statement. Its heartbreaking for everybody, our family, the scott family. I would hate for this to happen to anybody. Reporter karen sharpe is still waiting to learn the fate of her son. I just i say prayers for both families. But we just take it one day at a time. Well have much more on the case in the morning on gma. Next, just like brad and angelina, these famous parents have adopted children from around the globe. Tonight the johnsons talk about changing the world from home.

When eating healthy and Drinking Water just isnt enough to ease my constipation i trust dulcolax tablets. I take dulcolax for dependable overnight relief and in the morning i am back to myself dulcolax, designed for dependable relief youre about to meet parents confronting the same challenges any family faces raising a house full of rambunctious children. What makes them different . Heres my nightline coanchor juju chang. Do you want short dresses . Reporter buying a fancy dress for a school dance is tough for anyone. But when youre just 4 feet tall it presents a whole different set of challenges. As you can see, trent and amber, along with their five children are all 4 feet tall or shorter. They say theyre the largest family of dwarfs in the world. Heigh ho heigh ho reporter they even call themselves the seven little dwarfs from the classic disney movie snow white. Why would you want to be known as the seven dwarfs . We happen to be seven dwarfs. And, you know. Call a spade a spade . I wouldnt say its who we are, its its literally what we are. Reporter theyre okay being called Little People shortstatured dwarfs. But certain names are hurtful. What are the names that are used . Midget. Thats most offensive. People ask, what do you want to be called . Frankly, we want to be called our names trent and amber. Reporter they may be the newest reality show stars with tlcs seven little johnsons. Theyre bringing the world into their hectic, threestory home which theyre renovating all by themselves. They refuse to modify their house to accommodate their small stature. You get averagesized furniture furniture, why . When they walk out the door, nothing is modified for them. I want them to go to their friends house and know how to adapt. Were teaching them independence and we call it inhouse training. Reporter they may be little but they have big hearts. And are raising their five kids including three adopted from the other side of the world, drawing comparisons to another famous couple. So i love that you were dubbed the brad and angelina of the Little People. We definitely take that as a compliment. We think theyre Pretty Amazing couple definitely. Being in the limelight all the time and that they stay strong and thats something that we definitely strive for as a couple and as a family. Reporter they had son jonah and daughter lit beth soon after getting married. But two difficult pregnancies took a toll on amber. At just 48 inches tall she grew 51 inches wide, making everyday tasks excruciating. Since she and trent have the same dwarfism gene the probability of losing a child was high. Your pregnancies were tough but they werent horrible . Pregnancy was very tough. I think, you know my body just didnt really like the whole idea of it. Reporter so the couple decided to expand their family through adoption. Bringing home daughter anna from russia, emma from china, and son alex from south korea. The social acceptance for dwarf children over in most foreign countries, you know, is their future is not great as your american typical child. You were saving them from a pretty bleak existence overseas . We dont necessarily see it as maybe we saved them. They gave us their presence. Theyre our children. I mean the least we could do is to be able to give them opportunity and give them education. Reporter a home full of Little People comes with difficulties. All seven johnstons have dealt with multiple surgeries. Back and brain stem surgery, then of course csections all the way down. Common in a lot of Little People. When youre a little person you can have back surgery, like my sister did, or you could have corrective ankle or leg surgery. Because of the bowing of the legs . Because of the bowing of the legs. Have you had it done on body legs . Both legs. I see. He had leg surgery. I see. That straightens it . Yes. It straightens it. Reporter even though dwarfism is classified under the americans with disabilities act, the johnstons say they dont accept disability. They dont see themselves as disabled. Amber is an active stay at home mom. While trent works as a ground supervisor in charge of a group of big burly guys who do landscaping and maintenance at a local college. For trent he talks about his size that spilled over into his professional life despite 22 years of experience. Do you think youve been discriminated against from a job perspective or in your career . Your wife is nodding. I have. In what way . All our resumes are the same. But when that 4foot man walks in that door, after the seven or six applicants before him have walked through that door, hes going to remember me. Reporter as the family grows up amber and trent have a whole different set of hurdles. Raising three hormonal teenagers. Which means learning how to drive, trying out for sports against averagesized kids come on keep the ball moving reporter and awkward talks about the birds and the bees. If you want to go to the dance youre going to listen to my rules. Whats it like being a teenager, normally developing theres boys theres peer pressure. What have you encountered . Like we dont know if theyre just wanting to date us because were sized, or they really like us. My dad wants to wait till were 16. What do you mean theyd only like you because of your size . Maybe they want to date us because were funnylooking. Reporter through it all theyve learned not to take themselves too seriously. What went through your mind . That im going to be getting a lot of people staying home. Funny, watching two Little People fall. I get the sense you dont let your size get in the way of your ambitions . None of us let our size get in our way. And we instill that on the kids too. We tell the kids at home when they come up and tell us, i cant do that or that. Dont bring us i cant. Lets go back and figure it out. Every parent is afraid to watch their child get hurt. Absolutely. And we are too. Or fail. We are too. And we are too and its very difficult to watch the kids you know come in last place in a race. But the way we look at it, you tried. And without ever trying, we would never know.
