They’re no longer allowed to own guns?
Felons can’t own guns.
Chapter 44 of Title 18 of the United States Code (U.S.C.), federal law bans convicted felons from possessing firearms or ammunition. (The U.S.C. is a compilation of congressional laws organized by topic and subtopic: Title 18 defines federal crimes and criminal procedure, and Chapter 44 (Sections 921-931) covers firearms.) It sounds straightforward enough, but when you unpack how that federal law works and factor in the complexities added by state laws and high court rulings, a much more complicated picture begins to emerge.
According to Section 922(g)(9), no one “who has been convicted in any court of a crime punishable by imprisonment for a term exceeding one year” may own or possess a gun. This rule covers all felonies, but does not apply to state misdemeanors that carry less than a two-year sentence. It also exempts several kinds of felonious white-collar crime, as well as felony convictions handed down in foreign countries [sources: 18 U.S.C. § 921; 544 U.S. 385; Williams].
Lest you think Section 922(g) is too lenient, however, read on: It also bans guns for (among others) fugitives, illegal users of controlled substances, mental defectives, illegal aliens, dishonorably discharged soldiers, renounced citizens, subjects of certain court orders and persons convicted of misdemeanor domestic violence. Violating these statutes can net you 10 years of imprisonment and/or a $250,000 fine [source: Rhode Island Probation].
