the US is also a piooner of the gang culture, which often seams to devide down racist lines.
The problem with racial profiling, is you risk furhter alianating the target population. With the case of our first teen peddle by shooting a few months back, the police know certain memebers of the community know who did it, but they've closed ranks. When the ghetto population don't trust the poooo-leice (trying to be cool and ***k the police sounding), you have to tread softly.
