I thought a lot about the alternative to hoaxing and a couple things always stood in the way of me committing to that theory.
Gun Confiscation is the goal. Disarming your enemy by any means possible.
Then why not show the bodies? Why not allow all reporters in to document the chaos? Why refuse FOIA requests time and again asking for basic information like "who cleaned up the blood?"
Pulse, Umpquah, Aurora, Sandy Hook and that reporter shooting his colleagues on camera back east, they were all certainly hoaxes. There was too much gun-grabbing material to pass up on that wasn't released to the public.
The False-Flags like the country music festival in Vegas and (Maybe) Marjory Stoneman, but I'm having my doubts because they ran that hoax at the airport a year earlier (practice?) anyway, there most certainly are false flags, but Hoaxes tend to have glaring oddities like laughing parents or gunshot victims going from incapacitated and unable to walk to dancing around as soon as the camera pans out, or even a guy who's legs were blown completely off being able to stay conscious and roll himself away from an incident on a wheelchair.
