Just like with police abuses, the fix for the problem is to shine as bright a light as possible on it until it's understood and can be addressed. For many people, at least, a clear understanding that not all cops are bad actors — that, in fact, the bad actors constitute an overwhelming minority of the population. (But also, unfortunately, that the problem in that case is exacerbated by the "thin blue line".)

Blocking people from talking about it — you know, "prior restraint" — is emphatically not the solution.
