That wouldn't fly here in most cases, violent crimes, he couldn't buy a hunting license here. That would prevent him from having one in his possession. So you need to check with your Fish & Game dept. I'm sure they are all different.
Rhode Island General Law 20-13-5 PROHIBITS the following persons from PURCHASING or POSSESSING a Hunting License:
Persons convicted of a Crime of Violence*
Fugitives from justice
Anyone declared mentally incompetent
Drug Addicts
Habitual drunkards
*"Crime of Violence" shall mean and include any of the following crimes or an attempt to commit any of them; murder, manslaughter, ****, first or second degree sexual assault, first or second degree child molestation, kidnapping, first and second degree arson, mayhem, robbery, burglary, breaking and entering, any felony involving the illegal manufacture, sale, or delivery of a controlled substance classified in schedule I or schedule II of §21-28-2.08, any violation §21-28-4.01.1 or §21-28-4.01.2 or conspiracy to commit any violation of these statutes, assault with a dangerous weapon, assault or battery involving grave bodily injury, and/or assault with intent to commit any offense punishable as a felony; upon any conviction of an offense punishable as a felony offense under §12-29-5 (domestic violence).
Penalty is a misdemeanor, punishable by a fine of not more than five hundred Dollars ($500.00) or imprisonment for up to ninety (90) days or both.
Felons cannot own guns. However, an ex-felon can. An individual can become an ex-felon in one of two ways: having the conviction vacated by a court, or obtaining a pardon from either the governor (state offenses) or the president (federal offenses). While not an easy or quick thing to accomplish, in some cases it can be done. At any rate, in either of those circumstances, typically gun ownership rights can be restored.
