Idiotic security rules

The Herald reported:

A security breach at Wellington Airport thanks to a passenger blunder is causing delays and a lounge evacuation.
A passenger “re-entered a screened area by going back through the exit doors after disembarking a flight” this morning, a spokesperson said.
“This means the entire lounge has had to be evacuated and all passengers are now being rescreened.” …

Local man Glenn Dwight said he was on his plane waiting to leave when the breach happened, and all the passengers had to be removed from the plane and rescreened.
He had been waiting at least 50 minutes and was still in the security area.

It is idiotic that because someone went through a wrong door, you force two entire flights to disembark.

I’m quoted in the article. I wasn’t on those flights but was part of the 200 metres security queue as they forced hundreds of people to go back through security again.

Someone should do a cost benefit analysis of domestic security screening. Has a single incident actually been prevented through screening?
