Two decades after the 1999 Columbine High School massacre and two months after five people were killed at an LGBTQ nightclub in Colorado Springs, Colorado lawmakers are drafting a sweeping ban on semiautomatic firearms.
If passed, the ambitious legislation would make Colorado the 10th state in the nation to ban the sale and transfer of certain semiautomatic guns while grandfathering in the state's existing ones. California passed its ban in 1989, and most recently, Illinois' ban was signed into law two weeks ago.
