First, there is no problem
I'd say cops being murdered in the street and protesters blocking hospitals is a problem. Of course these may be isolated incidents, but I am under the impression quite a few people think it is a problem.
I also think people being killed by unjustified police violence is a problem, even if such are very few.
I think the general attitude of some communities towards police are an issue, as may be the attitude of police towards some communities.
Violent protests and looting sure are a problem.
Hell, even civilized, peaceful protests are a clear sign that there is some kind of problem.
It may even be a problem of perception only, where people protest without what you and I would see as proper reasons to protests.
Maybe even the protests and looting are isolated incidents, blown up by sensationalist media and YouTubers. In that case the media coverage of such events is a problem.
Whatever the real deal may be, it seems there is some kind of societal issue at play, even if it is just an issue of perception.
And I don't think such issues go away by blaming one group or another without thinking about society as a whole.
The choices a society makes have an impact on its (future) issues.
And everyone in a society has an impact on the choices and culture of a society.
