I think this really is going to be a huge problem. LE all over the US was looking at ways to deal with racism in the police department . Many departments admit there are issues and they were doing things such as in Dallas to improve. And they sure had!
Things have to change in a different direction now. It is not for me to say how. I think these protests and now the killings show that there needs to be dialogue engaging the POC because LE cannot go out in uniforms with no protection, I think everyone can agree that is no longer possible. Trust has to be established between LE and POC. . Working together. Communication. Making solutions together. Listening. Being heard. People's concerns , LE and POC, must be heard and acknowledged. The concerns cannot be dismissed. That causes resentment and lack of cooperation.
Like all issues, though, only a small portion of people will engage in the work. Then when a decision is made, those that did not participate will start in on how terrible the decisions are.
