Uhhh.....
That I think is missing the central point. First it's about whether we recognize that others would find such things to be a sacrifice of freedom, privacy and dignity, and that they have a constitutional and practical right to their views. As opposed to thinking they should all share our/my/your views.
Secondly consider the following:
Suppose we were playing the game of junk touching and as a result of that "consensual" encounter something seems to be in your pocket:
- three hemp cigarettes OR
- a copied CD OR
- $4200 in cash.
Then I call law enforcement.
Then they check and you have a traffic fine not paid from a neighboring state from three years ago, and there has been a warrant for your arrest that you never heard about.
Third, apply the above to the TSA procedures:
You hurried to go to your flight and at the last minute realized that you had one of the above items 1, 2 or 3 on your person. You turn around and try to exit but they won't let you.
You are going to a little room handcuffed, buddy.
Suddenly you are in world of hurt and it didn't have to happen. It occurred as consequences from the premise that your rights could be given up without reasonable cause for the search, and that some sort of administrative bureaucracy could dictate how that was going to be done.
TSA in "preventing terrorism" is also going to enforce any and all other laws that they decide they want to.
Drugs? That's terrorism.
Cash? That's terrorism.
Traffic ticket warrant? Not terrorism but let's call the policeman over. Can't let that slide, can we?
Starting to see little bits of a problem?
