Just play the game. Get the metal out, throw the bag in the machine, take off your coat. Is that really too much to ask?
See, it's all about compromise. We want your airport to be better protected than a trainstation, yet we don't want a full cavity search on every passenger. Everything in between will allways be a compromise.
And compromises are by definition not perfect, they will always cause debate.
If you ask passengers to take their laptops out of their luggage you will achieve a greater level of security. But then pilots on pprune will scream rape and murder, because it slows things down even further.
When you alleviate certain rules to speed up the security process, the same pilots on pprune will say: see, this security has more holes than a Swiss cheese.
So just play the game. And let the security-agent do his/her job.
