Only fact we do know is that the shooter was a devout (D)onkey. Hey Boots, Jojela2, Klastri Allie, Homer, Brad12, Nanakoolaid and a few others fanatics, I think you all should stop by the FBI office and turn yourselves in and any possible weapons you might have before you do anything crazy like your fellow Democrat shooter.  
Various news sources:
"Shooter, Stephen Paddock, a registered Democrat - originally from Florida."
