Whilst I understand that governments have to take threats to the safety of their citizens seriously, questions need to be asked about the extent to which these security measures are eroding our civil liberties, i.e. the very things which make our society worth living in.
I'd like to live in a safe world, but I'd rather live in a free world. And if the cost of living in a free world, where innocent human beings are treated as such, is a small risk of being attacked by nutters, then that's a cost I'm willing to pay. It simply has to be, or else our society is no better than the one these loonies want.
