That looks the bart train station. Technically you are not supposed to eat there. But its pretty much never enforced and no one cares anyway.
I'm willing to bet he wasn't the only one on that platform eating.

Isn't that a public place? I'm not familiar with the California laws but that seems random as hell.
I can see that. They should put trash cans around but even still it's up to the people to maintain the stations clean. But then again I'm sure there's plenty of homeless people so not everyone gonna be throwing their trash away and whatnot.According to bart rules you cant have food in paid areas. Sounds dumb I know, but seeing how dirty bart is I can kinda see why.
Either way I've never seen this enforced on whites. Or really anyone. The cop just has shyt priorities.
