Its an unskilled job with zero qualifications.
The qualifications for TSA agent are exactly the same as that of janitor, gardner or dishwasher.
But those jobs don't have nearly the same rate of criminal element....and they DO a positive service for society.
The difference? Not only does TSA attract those with no skills, it also attracts those with a desire to exert power over others. Furthermore a dishwasher has -accountability-. If they break a dish they can't hide behind "SSI"
Very bad combination and its no wonder that the TSA bad apple tree is constantly raining bad apples.
