The attack on the Route 91 Harvest Festival, the Las Vegas massacre killing at least 58 people and injuring over 450 more, opened up debate on the availability of guns. The same questions raised after Columbine, Newtown, and Orlando.
Yet very few changes were made after these mass shooting tragedies. And some laws became more relaxed. In 2004 the federal ban on assault weapons expired. The ban, enacted in 1994, fails repeatedly to be reinstated in Congress.
