This will just end up as something to harass citizens with...
As an aside, the last time I traveled by air, I brought my GPS unit and its "throw on the dash" mounting base. We were flying into Vegas to stay for a few days, and then driving to Phoenix to see my folks before flying home.
The base is a solid, heavy piece of black rubber filled with some weighting substance like sand, and it has a smooth plastic disc for mounting the GPS unit's suction cup to the base. I had the GPS and the base in my carry-on backpack, and the density of the base going through the xray triggered a warning, so they pulled me aside to search the bag. Fine, I thought.
Instead of taking the base out of the backpack and inspecting it, they completely emptied the bag and examined every single thing, from flipping the pages of books and magazines, to opening a deck of cards, inspecting the peg compartment for my cribbage board (a little metal slider with a sharp edge, perfect for slitting throats, BTW), and everything else in the bag.
They got to the base. The agent held it up for examination, and says to the other agent, "This is the item. What is this?" The other agent says, "Oh, that's a GPS base."
Then the first agent says he'll have to swab it down. He took a little moist towlette and wiped every inch of the base, thoroughly and meticulously, almost making sure to take extra time, agonizingly explaining to me every step of the process... "Now I'm going to open this towlette treated with a chemical able to detect explosives. You'll need to stand back. Now I'm swabbing the object in question, making sure that if there are any explosives on the object, they'll be detected. Now I'm placing the swab into the reader, and we'll wait for the result."
Guess what? My GPS base triggered an explosive warning. Two additional agents converged onto the location, as they informed me that I was to receive the patdown. I suffered that indignity while my wife, sons, and little daughter stood by and watched.
I couldn't contain myself. When he stood up from feeling my crotch, I said, "How can you people live with yourselves? How do you sleep at night and look at yourselves in the mirror every morning knowing that what you do for a living is so completely useless and despised by everyone you confront at your job? It's not like you're cops, keeping people safe. This is a joke."
"Just doing our jobs sir."
"Well, you're making a choice every day to come to this. If I were you, I'd find respectable employment that didn't make me into a useless piece of sh*t."
With the curse word, he looked at me sternly, "Keep talking sir. Keep talking."
My patdown was completed, so in a moment of boldness, I said, "Whaddaya gonna do, arrest me? Phhht." I walked away, and that was the end of it.
But man, are you spot on Glock. These piece of sh*t "law enforcement" officers - and let me be clear, I'm not speaking of all cops, but of the insidious mission-creep of all badged authority - are looking for new ways to harass. They want us out of our comfort zone. They want us to become used to ceding our liberty to their badges. Or perhaps more correctly, now that most people are used to ceding their liberty to their badges, they feel more and more emboldened to harasss for its own sake under the guise of "keeping us safe".
