A lot of you might have heard about micro-stamping, but this is a new one for me. Apparently, there's technology that can imprint a gun's make, model and serial number on a shell casing every time the gun is fired. California's considering a bill to require micro-stamping on semiautomatic guns. There's even talk of a national law, too.
Supporters say it'd help police solve more shootings. Opponents worry that it'd make it easy to frame people by throwing down shell casings at a crime scene.
