People tend to focus on what the people can/should be doing, especially in this thread, but when you ask those people about what the government/cops should do you hear white noise.
To answer your question, there needs to be an overhaul of every police department in the country. The FOP has to go, contracts need to be renegotiated, policing should no longer be a full life job but one that ends after a set period of time, a minimum of a college degree or four years work related experience, be able to pass mental health tests, be able to pass drug tests (specifically for PEDS and steroids), have required community relations courses, preferences in hiring given to those from that area, no history of alcoholism (the amount of cops who abuse alcohol are very high) and a return to restorative justice and cops walking the beat as opposed to the shit in the vid I posted.
Short of that, the only way it will be "solved" is through murder and that's not going to solve it, I understand, but you watched that second vid I posted and you know that's not a way to treat someone. However, if you keep treating people like that they are going to go nuts.
