Actually just about all cities with a large black urban population have a substantially higher murder rate than those that don't. Los Angeles, Oakland, Dearborn, Flint, Chicago, etc...the list goes on and on...They perpetuate a culture of violence in urban settings. Not so much in suburban settings. The environment seems to be a big factor.

Having career goals other than NBA or rapper = acting white.
Avoiding foul language / speaking courteously = acting white.
Obeying the same laws as white people = acting white.
Not trashing one’s own environment = acting white.
Husband + wife + children = acting white
Refusing to act white = street cred.

Lieutenant or above in drug gang hierarchy = street cred.
Prison = street cred.
Teardrop facial tattoo for each homicide committed = street cred.
Taking down a white cop = the ultimate street cred.
