I wonder how much of a background check is performed on potential employees. It seems that the flying public is unduly scrutinized while the thieves have free rein to take their possessions. I'll drive, thank you.
You have to understand that there are insufficient resources to be doing background checks on all those folks. The TSA has far more important things on its plate, for example issuing all those credentials to the mule skinners who pull canal boats! They just prioritize and do the best they can.
