While Barack Obama and his Administration are concentrating on restricting and seizing Guns from law-abiding Citizens; gangs are responsible for most of the violent crime in the United States.
The Barack Obama Administration has armed vicious Mexican Drug Cartels and MS 13 (which many consider the most vicious and violent gang in the World), with assault weapons through the Obama 'Fast and Furious' program.
The Bureau of Alcohol, Tobacco, Firearms and Explosives Tampa Field Division, ran a gun-running investigation that was walking guns to Honduras using the techniques and tactics identical to Fast and Furious. 1,000 of those guns were sold to MS13 buyers.
