So, I tried to post it earlier, but couldn't figure out how to get the video out from behind the paywall.
Basically, WaPo got high resolution versions of the security cam footage.
... I don't think this dude fired a single shot.
I think that the Secret Service guy who was shot, was shot by another security guard.
Basically:
O
[]------------>
X
Where the arrow is the dude running through the metal detector, O is SS dude who was shot, X is other guard.
As the dude is running between the two, X fires off at least 3 shots, tracking running dude.
O appears to become injured very soon after X fires one of those shots, where that shot is fired while X is basically pointing at O.
But you never see a muzzle flash from the shotgun.
You do see them from X's pistol though.
Also, in the audio of the event, everything I've seen and heard... all the shots sound similar.
And these shots all would have occured in the same space, the same hallway.
A shotgun blast does not sound like a pistol shot, its... significantly louder, has a different kind of waveform.
What is even more insane is that apparently the assailant was never even hit.
... So the only actual injury in all of this was friendly fire.
Like yeah its still insane to sprint through that with a shotgun... but nobody even hit the dude?
Fucking clownshow security.
Also, it would be immensely simple to figure out what actually shot the SS dude O.
His bulletproof vest caught the shot, preventing him from being more seriously injured.
So... if it caught a bunch of buckshot... it was the shotgun.
If it caught a 9mm... it was friendly fire.
