one more personal anecdote and that'll be it from me
many years I ago I used to train at this dojo in Oakland. it was the dojo that was notorious for being welcoming to women, trans people, etc as well as punks, which especially 20 years ago was pretty unusual because most jiujitsu spots were rife with cops. one guy I trained with was a British Sikh who'd emigrated. real nice guy, a bus driver with two kids (he'd married a Mexican-American woman, classic Bay Area combo). we got to be friendly and he me invited to go with him to his gurdwara one weekend. I'm totally irreligious but always up for an interesting experience, so I said sure. on the way there, he confessed to me that he'd applied and been accepted to the police academy. he asked me not tell anyone at the dojo, because he was aware of how anti-cop the vibe was there and he thought people would ostracize him.
then he explained to me why he wanted to become a cop. he told me that as a kid, growing up in England, his parents had had a corner store - a British stereotype, I'm aware - and that they'd had problems with racist NF types in the whatever, late 70s-early 80s, and that as a kid (he was probably about 10-12 years older than me) he'd seen cops come and take his parents reports after the vandalism or intimidation or idk and help them with it in some way. it made him want to become a cop someday. the purest possible motive. he said he was nervous to tell me because I thought I'd judge him, so this was like his justification.
I remember very clearly being like look, your heart is in the right place, but you realize that's not what you're going to be doing as a police officer, right? in fact, you're going to spend the large majority of your time enforcing policies built on systemic racism, not combating racism. if you want to combat racism, you'd be vastly better off doing some kind of community organizing (and nowadays I might say, and/or run for local office or otherwise get to some place where you can actually influence policy). you'll have a mandate to constantly arrest people for bullshit. you'll probably get into situations where you have to crack heads.
idk what happened to him, we lost touch after I moved away, but if he did become an Oakland police officer then he was in a department that, like Chicago, eventually got a DOJ consent decree to curb things like violence and systemtically racist pretextual traffic stops. And he likely wound up cracking heads while on riot duty after a BART cop killed Oscar Grant. you know what he almost certainly didn't do? help convenience store owners combat racist skinheads.
so there you go. the farthest thing from a bastard, best of possible motives, worthless before a fucked-up institution.
