I recently went through LAX screening. I accidentally left my Leatherman pocket knife in my carry-on bag. It's a stainless steel knife with a 3 inch blade. Of course, I didn't know this until I arrived at my destination and unpacked my bag. The TSA screening completely missed it, even though it wasn't even remotely hidden. I think it is time to take a review of the TSA procedures and start to dissassemble the securit…
it's also completely ineffective. It's effective at the theater aspect. To ask for more is, arguably, unreasonable. I strongly suspect the average traveler or voter would be able to judge between what's good security and what isn't. I recall discussions such as arming flight crew immediately becoming political, overshadowing rational discourse.
Also have a trained pro sitting on the sidelines pulling out people he finds suspect.
At a later point, maybe you can replace the fancy looking stuff with equipment that actually does something.
