Not really surprised, I took an aircraft from CDG last year and on arrival at our destination we had a untagged suitcase on board, found to be containing canabis.!!!
Allso know an F/O who had his swiss army knife confiscated, only to replace it with a large stanley knife blade and gets through the X Ray machine every day!!!!
So forget the bloody locked flight deck door and get the ground side of the operation cleaned up.
