In November, Roman filed a lawsuit alleging that the federal government was preventing him from exercising his Second Amendment right to own a handgun. In his complaint, Roman said the law prevented him from buying a Smith & Wesson 638 revolver from a federally licensed dealer for self-defense. The gun dealer, Firing Line of South Philadelphia, refused to sell him a weapon because a 1968 law forbids anyone who uses marijuana from owning or using a firearm.
