What do you mean? You mean standing in the security line (potentially for hours) doesn't really make us any safer on flights?I thought the lithium battery issue was related to pallets of them being transported as cargo, not individual batteries, but then it just snowballed to batteries = danger.
I have zero trust in any sort of safety regulations though. Too much of it seems designed to just create the appearance of safety.
While the TSA does help improve the security of passengers by finding things like guns & knives, and even explosives, I think many people would generally agree that they lack fully trusting the security measures in place. I can't tell you how many times I've gone through security, observed the way TSA agents were behaving, and thought to myself "Really? These are the people that are supposed to be keeping us safe?".
