I think you’re correct.
And for parades or other events, the bolts were taken out or otherwise disabled.
I seem to recall there were a few times where it was commented that bho had LEO at events with empty holsters too...
Whereas I’ve seen many photos of Trump with LEO and they don’t appear to ever be disarmed.
In 1993, Rolling Thunder was diverted AWAY from the White House. The whole route had to be changed to accomadate Klintoon’s contempt for our Military Veterans.
I was used to the old route and was disappointed that we no longer roared past the White House.
Klintoon was just the beginning of the contempt for the military that The Lyin’ King and Bribedon have continued. Grrrr.
