Please use common sense.
Security STOPS bombers from placing bombs.
They stopped nothing.
Only the use of the remains of their former stock of detonators, improvised with some other common items, saved the day.
Without the chemist, they were in a quandry, being hunted, and having some more work to be done by incompetent, but zelous, drones.
BTW, love your screen name.
...or this is a copycat situation. Too early for conclusions = common sense.
