At the minimum : guilty of Dereliction of duty.
If you look at this one event, I would be charitable and go with dereliction of duty.
However, taken in context:
Biden’s “time to put Trump in the bullseye”
Lawfare attacks
FBI disinfo with Hunter’s laptop
50 spooks letter
No rooftop security @ 150 yards line of site
Outsmarted by a 20 year old
Gunman spotted by civilians 3-4 minutes prior to shooting
No reaction by LE until Trump shot
Trump the new Hitler meme repeated endlessy by mainstream media propagandists
Etc., etc. etc.
Looks more like a planned lapse. I have trouble believing the SS is this incompetent.
If you look at all the coordinated and implied threats by the Biden regime, what is the logical conclusion?
