"Your job is over if you [pull the candidate off-stage over a false positive]" is clearly the wrong rule - are you sure it's really like that?
Creating an artificial knife's edge is terrible management. If the priority is to keep the principal safe, then you need to be allowed to err a bit on the side of caution. It's a bit of a kerfuffle, but what really is the harm if Trump is held backstage an extra 10 minutes while security re-sweeps a roof after a suspicious report, or is even quietly interrupted by a couple of agents mid-speech and comes back out after 10 minutes to finish his event? Surely much less than his getting shot.
