You’re right. The honest black family bears the burden of the violence...
Not just hones black families, but all honest people. If more criminals were shot by their potential victims, crime would decrease for a couple of reasons: The obvious, dead criminals have a very low rate of recidivism (but still vote the straight democratic party ticket) and the some of the living who have criminal inclinations would be somewhat deterred by the possibility of more than a judicial slap on the wrist. Of course some decide on a life of crime regardless of the consequences, but then they would be eventually stopped by a bullet.
The government and the police HATE individual self defense for a couple of resons, first if citizens were more effective at stopping crimes then there would be less demand for donut sucking cops pulling down fat salaries at taxpayer expense, and secondly, if too many citizens get the idea that they can defend themselves against disorganized predators, then some might get the idea that the government is the biggest criminal enterprise of all.
