To stop violence or at least slow it down, is to talk to the society and go to schools around the country and put up signs around the city. That should help. Hopefully that will help at least a little. I haven't dealt with violence that much. For us Asians , we have violence against each other for power.
Violence mostly starts by people disrespecting each other.
If other gang members disrespect us, we disrespect back harder. If you join a gang, that means you're asking for violence to be a part of your life. Some people join gangs and try to fake the funk. That's why there are suckers who are dead or on the run. Revenge is one of the important things for being a gangster.
