I'm no expert but this guy makes sense to me. Forensic acoustic proof of SECOND shooter in the Las Vegas massacre A plausible scenario is that the government did it because they want more people to be pro-gun control. If martial law is ever declared, all of those guns in circulation will make it more difficult for them. Maybe they want to declare gun ownership illegal and collect as many guns as possible before they declare marshal law. The more pro-gun control people there are, the easier it will be for them to declare gun ownership illegal and collect guns. It's just a theory.
