l.z. granderson writes, progress doesn't come from one verdict.aving one of those three cops with chauvin that day intervene to save floyd's life. as long as good cops still need a video to go viral before turning in bad ones, we'll be in the same spot we were the day before floyd died. is he right? >> well, there's a possibility that he's right, but what i've seen across the country and what chief ramsey has seen is the change. a lot more conversations about the duty to intervene. so i think this was a very important message to all law enforcement, even -- even though this case was easy to see how bad it was, we still have to remember that police officers have to remember their fundamental duty is to serve mankind. and they have to intervene when they need to intervene. >> well, it's interesting. in the george floyd justice in policing act, the proposed police reform, duty to intervene is one of the changes. training on that in effect. reinforcing training on that. but also other steps. banning chokeholds, ending or overhauling qualified immunity
