From The Truth About Guns:

Many have argued that there’s no reason to deny convicted felons their guns rights once they’ve paid their debt to society. If they’re deemed safe enough to release from prison, the thinking goes, why can’t they exercise their Second Amendment rights as they would any other?
This seems particularly reasonable in the case of felons who were convicted of non-violent crimes. Now the Firearms Policy Coalition, along with the Firearms Policy Foundation, the Second Amendment Foundation and others have filed a brief in a case against a man who was charged with possession of a firearm following a felony fraud conviction years earlier.
