Makes you wonder doesn't it? Nuclear material, no problem, bring it on board. A can of Coke? No I'm sorry sir, you'll have to leave that here.
Unless security screening is going to take 2 hours a person, anything more than a basic metal detector and xray machine is a waste.
Enough with this psychois we have for 'security'. We had 9/11, then we increased security, then some guy brought a bomb in his shoe, so now we take of our shoes, then someone planned to try liquids, so none of that, now it's radioactive substances.
Here's the interesting part: airport 'security' stopped none of those incidents. They were all foiled the old fashion way (excluding 9/11 unfortunately). All this added security has gotten us no where. By the time the security folks implement a system the bad guys have moved on.
Let me take a can of coke on the plane while wearing my shoes. Please!!!
(For those of you wondering why I say two hours, think about biological agents that could be, very effectively, used on an airliner... If someone is willing to kill themselves, well, pre-infect, then cough... Stop that with security!)
I don't care what you think of my opinion. It's my opinion, so have a nice day :)
