I mean their officers keep getting caught posting racist shit, participating in racist chats, police unions regularly donate to republican politicians, and they murder black people so often that the phrase “driving/walking while black” is common slang for when the aforementioned African Americans get gunned down for every day misdemeanors.
So, every police institution? I’m sure there are exceptions, but there’s enough of a preponderance to safely assume it and the data bears that out.
