It's just the hidden hand at work as usual, here's the timeline:-
Given that the first one in recent years, Sandy Hook, turned out to have actors involved (see below), and the Las Vegas one had multiple shoots according to witnesses, it appears it's all part of a Globalist 'Ban Guns' Problem > Reaction > Solution process
Hunger Games illustrates the dream Globalist end scenario i.e. they have weapons, you don't, they treat you like dirt and there's nothing you can do to fight back
