It allows people who have been found by a court to be mentally defective, people who have committed multiple violent felonies, and people who are illegal drug users/addicts to legally carry firearms. It is worded in such a clever way so that most people who don’t understand the law would gloss right over it.
The catch is the guns have to belong to the Government.
Our national policy is that it is okay to be legally crazy, a multiple violent felon, and to be a user of illegal drugs while carrying a gun… so long as you work for the government.
