So this makes it I'd say 50/50 IMO that either the motive was a personal grudge against some misfortune he blames Trump specifically for a la the assassination of Shinzo Abe, or that he was a gun nut who didn't want to surrender his Common Law AR-15 nor his Common Law stash of cocaine laced LSD at a security checkpoint, and went up on the roof to watch the show until he finished off the entire stash in one go and the demons told him that there was someone charging his position through the stage or something.

I'm almost more inclined to believe the second one because the first shot that actually caused the ear bleeding is now rumored to not have actually hit Trump but instead the Teleprompter which sprayed glass Shrapnel at the felon in chief which is what actually cut his ear.

This would imply that the first shot which he'd have the most opportunity to laze the shot for was not actually aimed directly at Trump as much as in the same direction as he happened to be in relative to the shooter. Unless the teleprompter was a lot closer to Trump at this particular rally than they usually are to the stage during most rallies on either side of the aisle.
