I definitely think the world has gone mad.
There is so much knee-jerk reaction going on nobody is paying proper attention to where the real threats lie.
I went from my crewroom ( within terminal 3 at Sydney ) up to terminal 2 to get a subway roll and a juice. I had to go through T2 security to acheive this threatening act. To get back to my crewroom I had to go back down through security, outside to gain access to T3, upstairs, through T3 security and YOU GUESSED IT, I had to undergo an explosives screening by the same guy who saw me come through earlier that morning.
Yet if I were a porter or cleaner or caterer my first stop could easily be the baggage hold of a 767 without one single security check.
I certainly am against complacency but cast the net over everyone or don't bother.
