This problem has been around for decades.
I remember back in 80’s in college sociology class.
I had discussion with very honest professor.
His explanation of problem.
Citizens in depressed areas tolerate crime, due to distrust of police and government.
Crime,drugs provide a form of income for those that cannot or will not get full time job.
It also provides for underground economy.
In addition in most of these communities people who are being victimized by gangs have a family member in gangs also.
Therefore if they rat out one gang retaliation comes in form of dead family member.
This situtaion perpetuates problem.
When I asked what could be done.
He answer was that the only way to end violence was to eliminate all gangs in said area.
Eliminate as in kill, no trials.
Further discussion with professor, he said that politicians and police had no incentive to end problem.
Politicians because they can always run on tougher anti gang platform.
Police because if they eliminate threats to community,they are not needed.
Pretty grim assessment of situation, but one I have never forgotten.
Powerful, still thinking about those statements. WOW..sounds as if he was right.
