I don't know what a frantic thumper is, nor do I have an axe to grind with DJ, however I know gross negligence when I see it.
To put it another way, how would you feel if you became aware that the aeroplane you were flying in had just had an explosive device removed from it, and yet no search had been done for any more devices before the aircraft was put back into revenue service?
Whoever was responsible for that decision deserves the sack at the very least.
To say 24 hours after the event that it wasn't a proper bomb, misses the point entirely.
