Looks like 50% are illegal and 100% have rap sheets a mile long.
I'm betting the two caucs on the front row are cops.
The legal citizen Hispanic population in California is enormous. Any random group is bound to look more or less like this one.
As for crime, it's hard to tell. They could be controlling the drug and gun traffic of the state, or they could just be a bunch of guys with ordinary jobs who like to ride on the weekends. My guess is more like the second.
When it comes to traffic violations, though, that's another story. They lose members every few months to accidents. Mostly reckless driving on their part, I think.
