Throttleback - exactly!
Julian - No further proof is needed at all! The extra security at airports just helps to make travelling by air even more ghastly and dehumanising than it is already, and by implication you're now suggesting that these security checks should apply to all other forms of public transport as well.... buses, coaches, trains, at this rate the whole world is going to grind to a halt!
We have to face the fact that life is a very risky business despite our mummies trying to wrap us up in cotton wool and protect us from all the dangers lurking out there in the big bad world. You're talking about one coach trip out of all the millions which take place every day of the week. You just cannot legislate for everything, or we'd all be conscripted as security guards.......
There's most certainly a balance to be struck between curtailment of liberty and the convenience of the public.
