I rewatched the broadcast to confirm, Trump absolutely inadvertently stepped out of the shot right as the shooter pulled the trigger. Trump went from standing with a hand on the podium, to leaning forward on it as he turned his head to his right.
The shooter brought a laser rangefinder which suggests he was aware of at least basic marksmanship fundamentals like bullet drop from gravity. He also had an AR-15, with a red dot and was laying prone with no visual barriers between him and the dais where Trump was about 130 yards away. Even a budget AR shooting basic af ammo can expect to shoot a 4 inch circle at that distance- plenty enough for a headshot.
Trump survived through dumb luck.
It’s genuinely incredible to see how openly evil the Likud/Khanist extremists in charge have acted, and how reflexive and hollow the counter-messaging has become from Netanyahu
