amy: kcra in sacramento spoke to nichols' sister keyana dixon and brother jamal dupree after they learnedbers what the police body camera video showed. >> for this to happen to him in this way, the pain is just -- i have no words. >> listening to how my stepfather played it out, it was horrif. out of all five officers, nobody decided to say, hey, this is not cool, let's back up. amy: talk about what is going to happen tonight. the police body camera will be released at 6:00 at this time, 7:00 eastern time. what do you understand you will see? what did it take to get this video released? >> it definitely took a lot of on the ground organizing, pressuring. i believe that if we did not have the protest on saturday a week ago, if we had not shown up in city hall on mlk day, showing up at the das office, if we had not continued to show up and pull it to people that were not responding to us, we would not be getting the video footage. to be clear, i don't need to see the video to know that tyre was murdered. i don't ever encourage people to experience that kind of trauma over and over again by
