Any place that has these huge housing projects, with all the gangs and violence that go with them are on another type of mentality. They grow up with the gang mentality and that mentality get's hardened as time go on. Death is just part of their world and they don't care when the bullets start flying.
Around here, you got pockets like this but not entire neighborhoods where you walk to one corner, one gang has control and 50 feet away, another gang has control. Put two different groups like that in the same 3 block area, and shat will always be off the hook.
The only thing that will change this is the people themselves stopping all this, I'm V-lord, my baby mamma is V-lord down, so my kid is V-lord from the first time they slip into this world. You have kids in those cities that are literally born into that shat. The entire family, generation after generation, are born into those gangs and they teach their kids that way of life and nothing else.
Different mentality.
