entities that i knew to be untrue by the department. so it just motivated me to to want to speak out and get this thing out in the media because, of course, i couldn t speak to my chain of command. i couldn t speak to the guys who were in the department because in my eyes and on paper it seems that they were part of the coverup. reporter: cavalier claims he has documented proof that excessive force on black motorists goes far beyond the troopers involved in green s death. he alleges black troopers and the state police are disciplined more severely compared to their white colleagues. we took these claims to the louisiana stitt police who said it wouldn t comment about ongoing litigation. since coming forward, cavalier has received notice he is being fired from his job. the culture of the state police is systematically racist. it is a part of the culture. it is a part of the culture. you have to be there to understand it and explain it. i m doing my best to expose the
trooper cavalier for coming forward. i think it is what our nation is saying we want officers to step forward when they see something is wrong. i think it is what the community wants, and i think leaders of agencies are asking their officers to do that. apparently it didn t happen here, but there are some leaders now that are saying we ve taken a step back with what is going on with trooper cavalier. it is interesting because he felt that he could not go to higher ups in the department because they were part of the problem, and he claims that the culture at state police there, that it is racist. do you think he had any other choice but going public? well, when i look at this investigation, it took 474 days for this investigation to get started. so it seems like there were no other recourses but for him to come forward the way that he did. you know, someone would say, well, he could have done something different but i don t think there was any right way when you are coming forward w
earlier this year, still trying and attempting to place blame on a crash. in the death of ronald greene, there were things being put out to the family and other entities that i knew to be untrue by the department. so it just motivated me to want to speak out and get this thing out in the media because of course i couldn t speak to my chain of command. i couldn t speak to the guys who were in the department because in my eyes and on paper, it seems that they were part of the cover-up. reporter: cavalier claims he has documented proof that excessive force on black motorists goes far beyond the troopers involved in greene s death. he also alleges black troopers in the state police are disciplined more severely compared to their white colleagues. we took these claims to the louisiana state police, who said it wouldn t comment about ongoing litigation. since coming forward, cavalier has received notice he is being fired from his job.
hero. reporter: ron hailey is the attorney for ronald greene s family and is also one of cavalier s co-counsels. he is doing this because he feels like this is the right thing, that he feels that the oath that he swore when he became a louisiana state trooper, that he is still upholding that oath by putting the public before himself, by putting the public even before his department in the name of making that department better. reporter: the troopers involved in ronald greene s arrest have been disciplined, but so far none of them have been charged. trooper cavalier says he hopes his coming forward leads to a federal consent decree on the louisiana state police. to ronald greene s mother, he says on behalf of the state police, he s extremely sorry for what happened to her son and hopes that his comments lead to the long-awaited justice he says that the family deserves. don. all right. nick, thank you very much. i appreciate that. i want to bring in now captain ron johnson, forme
