He wants to meet with the gangs? Well, that's nice. Is he going to meet with all the gangs and all the other black killers across the country?
Go to any fairly large city news site (CBS, ABC, NBC, FOX) on the internet and read the morning news. Generally without fail every big city in the country with a substantial black population will have reports of shootings, stabbings, assaults, killings of black people usually by other black people.
It's nice that one "famous" black person (whom I've never heard of) recognizes the problem. But until the overwhelming majority of black people understand that they themselves are causing 99% of the trauma in their communities will things start to improve.
