I see your point, the agents aren't really well trained typically. It is less than ideal. If creates hassle for your average flyer and doesn't significantly improve safety. The fact that I have taken liquid through over the limit demonstrates that.
And yes, I meant your carry on bag. I didn't even think that could have been interpreted in another way. I only fly carry on so the thought of checked bags wasn't in my mind lol.
Well I already knew they were evil. Another reason to not have them.
