Until it happens to them, they will remain brain dead.
For my dad, it happened in the 1980's already. However, unlike most victims of going too far police, he got his pound of flesh. I doubt he would get it today. It still cost taxpayers of the village over $2 million dollars (in the 1980's) to get those cops fired. (two street cops and the chief)
Did that department learn anything? Nope, not a damn thing. They were recently in the news again for going too far. Laws were broken by police, again...... They got busted again. Who knows how many millions it will cost taxpayers this time.
