Maine joins a dozen other states with similar laws, requiring that buyers wait 72 hours to complete a purchase and retrieve a weapon. The law is among several gun-related bills adopted after an Army reservist killed 18 people and injured 13 others on October 25, 2023, in Lewiston. Do you agree that states should require a three-day wait period for gun purchases?

The new law wouldn't have prevented the tragedy — the gunman bought his guns legally months earlier — but Friday's milestone was celebrated by gun safety advocates who believe it will prevent gun deaths by providing a cooling-off period for people intent on buying a gun to do harm to others or themselves. Gun store owners complained about the guidance, released just Tuesday, and the loss of sales to out-of-state visitors during Maine's busy summer tourism season. They also said the waiting period will take a toll on gun shows. Critics of the law have vowed to sue. They contend it harms only law-abiding citizens while doing nothing to stop criminals from accessing weapons illegally. They also contend people who intend to harm themselves will simply find another way to do so if they are unable to purchase a gun on the spot. Do you think if critics sue, they will be successful in reversing this law?
