I think everyone who has an opinion like that should actually go through an LEO academy themselves with the whole "if you hesitate your dead" thing, too.I still feel strongly that LEOs, at some point in their careers, should have to put in some significant time in "social work" or something equivalent. I'm not sure exactly how this would work - one week out of the year spent doing social work or an hours requirement prior to starting. I know there are some departments that do training in some of this, but I don't know that it's enough.
I just feel like with social work you get a real understanding of other people's problems, particularly those at the bottom of the socioeconomic. You come to understand all the obstacles in the system for a lot of people (e.g., rarely, if ever, is it because somebody is just lazy) and learn all the other options there might be for somebody other than locking them up for the night, etc. You get a real feel for being to talk things out with people from diverse backgrounds, because a lot of the time there isn't much you can do for them other than being a good listener. I spent a summer doing this type of work and I still think back on some of those lessons learned almost daily.
In sum, it just seems like a lot of these LEOs suffer from the "if all you have is a hammer, everything looks like a nail" problem - they are trained extensively on aggressively controlling suspects, so this is what many of them go to in a situation where they sense any risk whatsoever, which is a different complex issue altogether (some risk used to be expected for LEOs - had to see a gun, not just somebody reach in their pockets). I don't know, but I've been thinking about these situations a lot in recent months.
I'll guarantee you that would suppress 99% of the "the cop did that because he was a racist" argument. The other 1% would be the valid ones.
