The reality is that this is just negroes bullying other negroes because a lot of black men consider black lives as cheap. Checking in is another way of saying extortion. Call the right people, throw something in the pot for protection or something may happen to you, and a lot of times by the same 'side' that you claim.
Them gang members will be quick to DP another black man or kill him, but when it comes to dealing with the white man or the Mexicans, the tone is completely different. If they don't get rid of it outright, hopefully they keep that 'program' over there in LA.
