Especially given the high risk of flying in the past decade we...
What high risk would that be? Since the big 9-11 panic, there have been exactly two incidents, both of which the TSA, curtailment of rights, scanners, and silly rules failed to stop. Both incidents WERE stopped by the passengers. Meanwhile, paranoid security has resulted in at least one death (security shot a guy dead because he was acting strange and didn't speak English).
The amusing aspect of this in the U.K. is that two panics are now colliding in an amusing way. We have the OMG terrorists! panic slamming into the OMG pedophiles! panic. It seems nobody wants creepy security goons ogling their children through their clothes.
Honestly, it's only a matter of time before some ill-thought comment leads a parent who is already cringing to beat one of those goons to a pulp like social convention tells them to.
