America's becoming the scary police state we all despise. And with good tech.

becoming? It's been this way for a very long time. Very few major media outlets cover the Democrat/Republican National Conventions, but you can watch videos online of the protests from past years going back quite a bit. Rage Against the Machine use to do protests at both the DNC and RNC which I thought was hilarious. It's very common for protesters to be smoke bombed, herded, arrested and detained. There are several…

I agree broadly that the Israeli model seems the one to follow. My understanding differs, however, in that it's not strictly profiling in the sense that carries heavy negative connotations in the US. I haven't traveled to Israel so can't comment, but I understand that in "profiling" the focus is on more objective metrics than an American might think when they hear the word -- e.g., physiological responses (sweating,…

None of those are the metrics they use. Despite being an Australian citizen with a very clean record, as well as having a very Western name, I was red flagged before I even arrived because of my country of birth. With El Al, you're interrogated before you board the plane. When you go to check in, there is a "pre check-in" where you show staff your passport and they check your name off against a paper list. That paper…

This requires direct mechanical coupling to the head. The air to skin interface is an impedance mismatch which causes very little of the energy to be transmitted to the brain. This is likely not a real concern.

The air pockets in your head will resonate quite effectively. The impedance mismatch in the air pockets can result in powerful vibrations. Your head isn't filled with 100% liquids and solids.

Quite right. Israel's El Al simply profiles everyone that flies and by doing so they obviate the need to use stupid, expensive equipment that does nothing other than bottleneck airports and cause frustration. The Israelis are the best in the world at what they do regarding air security. The West has considered using the same techniques and they likely should. I'm not opposed to profiling if the person fits the profil…

El Al security is not a good model at all. I'm still yet to figure out what they achieved by seizing my backpack (that had all of my personal documentation) and damaging my brand new MBP 2016 and Pixel tablet (by very clearly dropping them a dozen times) had to do with security. Especially when they lied about putting it on the plane and I arrived at Ben Gurion with literally nothing other than a passport in one pock…

I support them not being allowed ever. But just like the totally ineffective body scanners at airports, too much money has been sunk in for officers not to use them. No one actually cares about the sunk cost fallacy.

Sunk cost fallacy isn't even what's driving that sort of thing. It isn't even that they spent the money and want to keep justifying it. There are parties with a vested financial interested in the continued use of such things.
