The issue is much larger than just guns. There is no economy where this people live. Kids are not going to school. So when all you have is to join a gang, what do you expect to happen?
Gangs are created not because of economy. Gangs are these kid's "family". This is due ot the breakdown of the black family structure.
over 70% of black children are born into homes where the father does not live in the home. Most of the mothers of these children have other children by more than one man.
Because kids need structure, they turn to others in the streets for that structure.
Unfortunately, the structure they receive has no redeeming qualities whatsoever.
Law enforcement is virtually powerless to prevent gang related crime. This is due to overbearing citizen review boards which place 'one size fits all' restrictions on police. These board members and their supporters are the very same people that complain to the government that the police are not doing enough to prevent gang crime.
Try being a Cop in a large city run by liberals.
Liberalism and government goodies created this mess.
Then we get stupid comments like "maybe there should be Marshall Law"...
