Gang Control (Worldwide)
I mean chances are most of these people never even leave their apartments (or the comfort of 2ch). Here they are out in public, creating art, clearly entertaining the bystanders and the cops have to come along and impose boredom on everyone because anything out of the ordinary is obviously bad. I guess for the record it's not just Boston cops who are brainless thugs and morons...it's Tokyo cops too.
(Okay...for the record it's all cops...)
