"As it is no one on the left is admitting to illegal drug or weed use as a factor in the mass murders occurring dispite illegal drugs and weed being what's at the root of say Chicago's own homocides. "
Okay, not sure about the rest of your point, but this part is ridiculous.
Chicago has so many murders because there is such a large BLACK MARKET for illegal drugs that gangs fight for turf and profit. Weed or drug usage is not what is causing the problems, but rather the selling of narcotics.
Legalize drugs, eliminate much of the black market, city is safer as a whole.
