I live just south of San Francisco and have started seeing those t-shirts everywhere.
The problem is not the t-shirt per se, but the ever growing numbers of people wearing them.
They will end up moving to the suburbs as middle and upper middle class adolescent gangsta wannabees with too much pocket money try to look "bad".
Yep. I understand that. I look at it as stupid. But consider that the parents set the example, out cruising on their Harleys wearing all the leather and imitation Nazi helmets trying to look like bike gang members. (Nothing against motorcycles, though harleys seems exempt from any noise ordinance)
I do not think most folks really know what gangs of any sort are into. Motorcycle gangs do some pretty nasty things; why would anyone want to even remotely resemble them?
At the Univ. of San Francisco Saturday night one of the Dons' redshirt players was wearing a stop snitchin t-shirt on the bench.
Which is ironic when you consider that the recent North Beach shooting death of CCSF star and USF recruit is still unsolved.
