In any case, if proof is needed that the way security checks are currently done at most airports is a pointless waste of time, including the limits on fluids, let me give it to you plainly just right here, in the hopes that authorities will finally put an end to them. I am sure more people are dying as a result of their travel time being so long and uncomfortable than are dying of terrorist attacks.
In most airports, so far as I have noticed, passengers first have to go through the security checkpoint with the X-ray scanners before entering the departure terminal and then on to their departure gate. Precisely, this is where the problem lies: there is only one common checkpoint for all the departure gates.
So all it takes is for a number of accomplices to each book a seat on a different flight, so as not to attract any suspicion, and then each of them can pass through security with their allowed dose of bomb-making fluid, or parts of a bomb or even parts of a gun. Then they can put it all back together in that great duty-free shopping lounge at Heathrow, for instance in the men's restroom to be discreet, and then the suicide bomber can take it with him to his plane. That simple.
At the very least, if such security checks are to dissuade people for real, they would have to be done at each departure gate, as this would make it much more difficult for a number of people to work as a team without attracting unwanted attention. But then again, this would still not prevent a few really dedicated individuals from going through anyway. So let's just forget about the scanners and let the people fly without having them take their shoes off. It's so annoying to have to do that.
So let me conclude this way: airport security is one more thing that I would definitely dismiss as utter crap, to be added to the list in the previous post.
