The Police cannot solve the problem from which gang violence arises. The police are a maintenance tool, not creators of culture, specifically economic relationships in America compounded racism from the country's inception.
Catching a gang member and throwing them in jail for an extended period of time is honestly for the best for everyone (Except the gang itself)
I went to a magnet school in the ghettos for middle school (They'd be shutdown if they didn't do that stuff)
People got jumped daily, people with red and blue bandannas ran everywhere, often picking fights with each other and many of those kids did things they shouldn't do
It was so bad, that me, a person who never ever racially stereotyped, nor even knew any of them, in elementary school went to purposfully avoiding black people and scary looking mexicans (I'm more than a bit ashamed of that, but it's true)
I'm not one for goverment spending but if for one thing those kids need to feel loved to keep them away from gangs and other bad stuff
