Street gangs cant last more than ten years? What do you think the bloods and crips are, most of their original individual sets are still active today and have spread across the country.Even the ones that have started in ny and nj have been around for years. MS-13 and latin kings have been around since the eighties and have factions all over the country not to mention the gangster disciples and vice lords in chicago that have been around since the 60s. Street gangs control the street level and mid level distribution of drugs in large areas which make them incredibly powerful on the street and in the prisons. Their also involved in fraud, extortion, prostitution and money laundering aswell as robbery. I aint sayin that lcn is done or anything but they are not in the position where they can muscle people without consequence. Most of their success was due in part to the fact that the government didnt really go after them till the eighties.
