@Real Music,
As I said on this thread - I think it was - I think the key matter is not just training, but police culture, which I take as somewhat variable in different departments, and that it is a matter of police culture at the top, which is why I'm starting to repeat saying, "Top down!"
I'm a Los Angeles person, a city I still love, but a city of much distress, and now living in, of all places, Albuquerque, also a town with some ugly blots on the police behavior blotter.
I've not lived in LA for almost twenty years, so I'm not so up on stuff, but there were at least efforts made to improve. I'm slow to pay attention to ABQ in general, living on the far side of town and not moving around much, but I need to read up more, and at least write letters, which my old self used to do. Actually, my old self would more often personally talk to authorities (assemblymen and women, people on city council), not send letters. Thing is, that was another instance of talking to the already converted, the people I already knew somewhat - but I found they wanted the feedback backing them up.
