There are a couple of horrible things about this article about a more efficient “metal” detector.
The first is that the method of personal invasion is getting less intrusive and more “efficient”.
The second is the game of “If I were a terrorist” that is being played in the comments.
The game “If I were a terrorist” is an impossible game to play. It’s pointless and silly. Mainly it’s a game that the people who want to take away our freedoms want us to play. Don’t play it.
The game to play is “If I had the right to be secure in my person, houses, papers, and effects, against unreasonable searches and seizures, and no Warrants issued, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized, what would that be like?”
