On October 25, 2023, 18 people were killed in a mass shooting in Lewiston, Maine. The killer's declining mental health was known to law enforcement since that May. On July 6, although he owned other firearms, he legally purchased the firearm that he would use in the attack. By August, he repeatedly threatened members of his Army Reserve unit that he would "shoot up" the base. He was hospitalized for psychological evaluation but released. Two months later, he carried out his nefarious threats at a bowling alley and a cafe.
In 2024, the Final Report of the Independent Commission to Investigate the Facts of the Tragedy in Lewiston was released, faulting both the military and law enforcement for taking no action to disarm and hospitalize the killer.
Before the Commission report was even released, the Maine legislature enacted a statute targeting any person who would buy a firearm: "Waiting Period. A seller may not knowingly deliver a firearm to a buyer pursuant to an agreement sooner than 72 hours after the agreement." As the timeline of events indicated, no relation existed between the perpetrator's vile acts taking place six months earlier and the 72-hour firearm transfer waiting period.
