I heard a figure of 6,000,000 items confiscated by BAA security people in UK in the last year.
Then there are the problems when returning from abroad - like my lad who forgot that his Swiss Army camping toolkit was in his pocket. Difficult I know considering that it was bigger than Linford Christie's lunch.
Pity they didn't spot the journalist's gun in his carry on at LHR/LGW (wherever) yesterday.
