The security theater needs to go on. In the meantime batteries represent a much bigger risk with potential in flight fires but I guess nobody cares enough to do anything about it.

When gate-checking carryon bags, staff told passengers to take batteries out of the carryons.

It seems like something that is high risk during flight shouldn't be left to passenger compliance with spoken instructions.

Earlier quoted context omitted.

Yeah, I flew thru Eindhoven Airport in the Netherlands a few years ago, and I couldn't believe they let me through with water. The security used something I would describe as out of an Iron Man film, they were zooming around a translucent 3D view of my backpack. (It was on an LCD display instead of hovering midair, but I was still impressed. But the fact they let me keep the water was even more amazing, hahah.)

I've seen this too in the US, the newer machines let them spin the scan around in 3D space and must make it much easier to tell if something needs inspection or not

Yeah these are pretty common in the US, but they're just not ubiquitous. Many airports will still have a CT machine next to the old one and it just depends on what line you get out in.

Let me get this straight. If the article is correct, the new capabilities are related to better detection of large liquid containers, not determination of whether or not the liquid is dangerous.

So - you couldn’t take large amounts of liquids previously because some liquids in large amounts might be able to be weaponized. If you were caught with too much liquid (in sum total, or in containers that are too large) they’d throw it out and send you on your way.

But now that they have the ability to detect larger containers, they… do what? Declare that it’s safe and send you on your way with it still in your possession?

This rule wasn't enforced anyway...

I travel a lot - and never take out any liquids. Have nail clippers and scissors in my carry-on.

Once I even had an opinel pocket knife in my laptop bag for a couple of months.

Travelled through Tokyo, Taipei, SFO, DEN, PHX, LAX, BOS, JFK, FRA, AMS, MUC, LHR - nobody noticed.

I seriously had forgotten it was there, so I don't do that now, but still...

Also, no large water bottles or similar. Unless on domestic flights in Japan, where this is totally fine.

IDK - security theater. But if it helps.

Recently flew through china where they asked 3 times if if i had a portable charger and made everyone sign declarations to that effect.

Famously Steve Jobs had a story about shaving time off of boot-up and equating it to saving lives on the concept of people sitting their waiting for the computer to boot up just lost that much of their lives. [1] I actually do believe there is value in thinking this way and it is one of my biggest arguments against TSA. Everything has a cost, including 'security' and 'safety'. If you look at the very real human toll, and economic toll, that airport security has caused any potential gain is out the window in just one day of costs from screening, and that doesn't even get into the privacy destruction this has caused. I think I would get way to angry to comment on that in an intelligent way.

But that is just one argument. My real anger at airport screening is that we have found it possible to fund and implement this level of screening, at massive monetary, human and privacy cost, but I can't go to my doctor and for a few pennies (sorry, those don't exist now, how about for a few nickles?) get a body scan that does all the 3d segmentation, recognition, etc etc etc. We could actually save lives if we put effort into this technology for people instead of for a sense of security. But we probably won't. Because fear gets money but solving real problems that actually impact people doesn't.

I believe the article mentioned density as well. I suspect that is extremely key in determining what it is, or at least determining if it is something really odd that should get additional screening.
