What next - the 2 a.m. knock on the door?

The government are having problems getting their legislation on holding terror suspects for up to 90 days without charge through Parliament. Quite rightly in my opinion - I have commented on this before. But what amazes me is to hear the Prime Minister trying to sell this idea by saying "the police have told me they need these powers, so they should have them". What sort of argument is that? Since when have we lived in a Police State? There may be arguments in favour of the proposal, but the idea that the police should unquestioningly have what they want is a highly dangerous concept.
