Whether they logically should or shouldn’t, it’s common sense that if someone has been mistreated by police, or as a child they saw their father or brother mistreated by police, or grew up hearing stories about family members who were mistreated by police, then they’re much, much more likely to (for rational and very human reasoning) be distrustful of law enforcement and view them as dangerous enemies to be feared. Most of the black people I’ve spoken to about this issue fall into one of these categories.
This is a very, very serious problem for law enforcement, and increases risks to both them and the public, and is not likely to fix itself until we can go a generation or two in which very, very few children see family members mistreated by police, or hear multiple and consistent stories about family members mistreated by police, or are mistreated by police themselves.
