Former Japanese Prime Minister Shinzo Abe was killed by an attacker wielding what police and other officials have described as a homemade gun, a rare shooting in a country with some of the world’s most restrictive firearm laws.
The attack’s link to a self-made weapon immediately highlighted the recent proliferation of so-called “ghost guns” in the U.S., largely untraceable firearms assembled from kits often purchased online that sidestep background checks.
