Have to agree with F3G. Last thing we need is people playing silly buggers to prove a point which we all know about already. Security are already very under-resourced and insufficiently trained and we don't need security people being taken off the job to bother with a prima-donna pilot who should be fired.
Thing that annoys me is that in other countries security is done so much better. In places like the States you can be through in a fraction of the time it takes in the UK, and the scrutiny is as good if not better. Whoever is running security in the UK airports should be dismissed for gross misconduct.
