Dying to fly?

Long waits in queues for security checks are now the norm, with passengers often treated like criminals whilst in the queues! Any humorous mention of bombs etc or strange behaviour can lead to aggressive tactics being used by the police and customs - where else in our country is freedom of speech and expression curtailed so much. Even grumbling to the person telling you to remove your shoes or your belt can lead to retaliation by the Border Agency staff.
Of course if you are fit and healthy, waiting in a queue, removing your outer garments, taking off your shoes, and removing your belt (at the risk of dropping your trousers!) may be something you can put up with. However those who are very young, or old and infirm, or those suffering from a disability, will find this very hard; have you watched an 80 year old man or woman remove and replace their shoes without help or even a seat? And in a very public place! Or a beleaguered Mum lift her crying baby out of the pushchair so that the pushchair can be scanned?
There is increasing evidence that passengers are suffering from substantially increased stress levels, and that that some have suffered heart attacks and strokes leading to death. This is in addition to those maltreated by the arrogant security staff and police who often need little encouragement to use bully boy tactics.
Surely it is time that this lunacy was stopped and a risk approach adopted to checking passengers for explosives and weapons.
By adopting a sensible approach we could end or substantially reduce queues for security, save airport costs, and make flying once more a relatively enjoyable activity.
