You're really bending over backwards to give Bart police a pass.
> San Francisco transit boss apologizes to rider detained over a sandwich

This guy was not doing anything illegal that doesn't leave evidence, but he does perfectly match my description of "people who are inclined to belligerence when requested to stop eating on the BART". Employed programmers and black people who do that are likely arrested at nearly the same rates.
I'm totally fine if you tell me "It's racist that cops only ever ask black people to stop eating on the BART." Or "It's systemically racist to apply the same rules to people who get a lunch hour at their jobs and people who don't." I'm just saying that arresting 84% blacks is not necessarily racist _by the cops_, because every one of those 46 arrests may well have a video like this one, and this guy deserved it.
Deserves to be detained for eating a sandwich? Beligerant for expressing how stupid that is? The police department apologized for this so even they don't agree with you. I think we're done here. Good luck.
I should say that purposely getting arrested on video to highlight the stupidity of the sandwich thing is a good tactic for getting it changed. I support the guy's actions if that was his intent.
