meant to divert attention from the real issue. Crime is more a part of life in poor communities, which is where most crime occurs, and is really a class issue rather than race. The crime rates in poorer white communities (white-on-white crime) where meth is rampant are similar to inner-city, black-on-black rates. And don't forget about gang banging in disadvantaged Latino communities (brown-on-brown crime). Criminals prey on those nearby, and those nearby almost always are people of the same ethnicity as the criminal. But you'll never hear the phrase "white-on-white crime" uttered, even after all the mass shooting done by loner white guys. The shooter is always immediately called deeply disturbed, but never criminal or thug.
Everyone knows the zimmerman verdict was a racist sham so black conservatives willing to write or talk (and get paid) about black-on-black are always trotted out whenever something like the zimmerman verdict happens. And they get up and do their duty.
