I want to point out the TSA has a tough mission, but the litigious society has compounded a bad situation.
Problem number one is that targeting previous groups that have hijacked planes and been responsible for almost 100% of terrorism in the last 50 years Muslims and commies would result in a law suit. If you are angry at these idiotic abuses at the airport blame your far left lawyers for creating this mess.
Problem number two is hiring practices. Many of the people hired appear to have chips on their shoulders. We do have this problem to a lesser extent in our office with officers whose verbal skills are appalling. I cringe when I listen to some of my peers.
Problem number three is poor leadership. Many of these supervisors are disgraces that are promoted for reasons unknown.
A better technique requires more common sense. Person X is a child with metal braces with a parent who is a ad exec. This should be sorted out with a five minute talk rather than a pat down. Person Y is a former Weatherman 60's radical. That person should get the full treatment. Person Z is under investigation as a money launderer.
This person should get an interview and pat down if needed.
Problem Four Dreadful Tools. Those not familiar with the tools would be shocked at the lengthy and often confusing tools the officers rely upon. Real life example a report says a person is not supposed to be in the country. The report says this suspect is white but in fact this person is a dark skinned Hispanic. Fortunately the reports of moles and scars are precise and the right action is taken.
There is an absurd fear of the scaning machines. I have zero problem walking into one as the officers should be professional.
