Why are you people complaining? This is all happening for your own good. It's all carefully designed to stop terrorism and preserve freedom, while enhancing the quality of democracy. The security employees provide a service for the travelling public. If you object to their procedures and/or don't bend over properly, you can choose to not fly, in which case you will be safe in the knowledge that no evildoer will ever manage to get on a plane because, as we all know, terrorists have always attacked civilian airplanes and nothing else, ever.
If they manage to do it, though, our democratically elected governments will attack a string of countries that may or may not support them. Now, that 'll teach them!
