Location: United States
Scariest fact: They’re absolutely everywhere.
Murder weapons: Guns, knives, and fists of fury.

A lot of the gangs on this list make the Bloods and the Crips look softer than people who wear Toms. No, the Bloods and Crips aren’t chopping dozens of people’s heads off or drinking their victim's blood, but the high number and large amount of criminal activity make them a significant threat in the United States. Hell, Bloods and Crips are heavy in the military. Neighborhood gangs actually present the most significant threat. This is that clear and present danger shit.
