Well, then this will be fun. Nothing shocks a fellow pax sheeple like demanding in the loudest possible voice to know what was wrong with the original screening where all the machinery inspected you and your carry-ons, and why, since there's so obviously something terribly wrong back at the check-point, all pax on the sterile side aren't being rescreened.
As the TSO's pause to catch their breath, demand, in mock horror/paranoia, to know how they determined which pax the original screening worked for, and which ones it didn't.
