Long story short, there is no way the American public will spend the money or submit itself to be inconvenienced and intruded upon to the extent necessary to guarantee the safety of every commercial flight,
Yes we will. The TSA has done a great job of social engineering. The latest move is to force compliance with 100% shoe removal under threat of an automatic secondary grope with a full torso pat-down. Absolutely brilliant!
Other examples:
1. How many people have gone out and bought "TSA-approved" locks?
2. How many people do you see wearing those silly things around their necks containing their IDs and boarding pass?
3. How many people willingly allow their vehicles to be searched with no probable cause at airport entrances or at public streets surrounding the US Capitol?
4. How many people allow themselves to be intimidated because they decided to take a picture of something?
5. How many people went out and bought mass quantities of duct tape and plastic sheeting?
The "I've got nothing to hide" crowd is live & well in the USA.
