Federal Firearms Restriction Act

The Federal Firearms Restriction Act was an act enacted by the United States government, sometime prior to March, 2019. It restricted the ownership of guns, making difficult for civilians to own a gun from at least 2019, onward. By 2026, ownership of firearms was considered all but impossible by anyone baring the few who could legally own them, namely law personal, and the few with the means to acquire them illegally, such as the Kitaki family.

During the investigation into a murder at Gatewater Land, Shi-Long Lang asserted that only someone who had access to a gun like Officer Meekins could have done it, due to America's strict gun laws. Upon being pressed by Miles Edgeworth, Shi-na reminded Lang that the law was called the "Federal Firearms Restriction Act".

The Kitaki Family
The Kitaki Family, a mob family from Los Angeles, had a number of illegal firearms. Due to it being almost impossible for an average civilian to get a gun, it was asserted that the the pistol used commit the murder of Pal Meraktis could have only come from was the Kitaki Mansion. The family were investigated on charges of the illegal ownership of firearms.
