It shouldn't be. And it all starts with the total breakdown of the 2 parent family in that community.
A 73% out of wedlock birthrate is going to produce a lot of young people with no boundaries or authority figures in their lives.
This woman is 38 and had 9 children with God knows how many different men. No father around. Rinse and repeat throughout the community and you see why young kids are shooting each other over nothing.
