I did have a long winded tyrade of abuse typed out for Mick and his stupid selfish I'm alright jack attitude but you have worded it much better so I've deleted it.
I'm sure Mick can look after himself, but you do not advance your views much by attacking him and impugning his motives rather than dealing with his argument. I don't think that it is respectable debate.
If he is happy sacrificing some of his (and his friends') liberty for security, that is a reasonable argument for him to make to which reasonable counter-arguments might be made.
