The government cannot manage to keep to a budget, prevent secrets from being leaked, craft sensible laws, collect the taxes owed to it, enforce its own regulations to prevent train derailment disasters, or do a multitude of any other things without seriously cocking it all up most of the time. I refuse to believe they are capable of organizing false flag shootings to further a legislative agenda.

It's more likely they merely politicize and highlight ones that occur for the same purposes.
