Naw, I'm not from there, but I lived in LA a while ago and I learned enough to tell people to do crazy shyt that they shouldn't think about doing.
Meh, of the various spots you can hemmed up in LA our hood wasn't the worst. Unless you're walking down in the Bottoms or shyt where you have no need to be I rarely saw a Blood go out of his way to fukk with a stranger in a public place unless they were already plotting trouble, even if you have the wrong colors on. Explicitly having a flag or a cap is pushing it too far of course, but there are tons of other places where that's true.
