That’s because security work it’s not a piece of cake.
All the regulations exist as tools to help you spot, secure and contain any and all contraband you may come across. And you will find that many troublemakers are crafty beyond all belief.
Inspect large and small aircrafts, take apart equipment to search every nook and cranny, thoroughly shift through all manner of luggage to find even the most nefariously (or hilariously) disguised contraband.
