I am still waiting for a proper security trade-off made by the ones "in charge". What does it cost to catch all those [strike]liquid explosives[/strike] water bottles when the plot (if any) to blow up a plane with a lemonade bottle didn't even get near to an airport. Both the shoe and the underwear bomber didn't achieve more damage to the plane than some scorched carpet. Is there a cost-benefit analysis for passenger scanning?
