No in a police state the Government uses the police to enforce it's will in an arbitary manner and the police are not subject to the laws that normal population are.
This is something different. Recent legistation (and attempts) such as ID cards, attack on trial by jury extended imprisonment without trial etc. is an errosion (some might say attack ) on traditional rights that we've enjoyed in this country for many years.
We don't have a written constitution so the European Constitution on Human Rights is the only thing that can stop politicians passing whatever laws they can force through parliament - and guess what people are now calling for that to be abolished too.
It's amazing how effective drumming up a bit of fear is when you want to pass some extreme laws.
It puts me in mind of Robert Bolt's a man for all seasons:
Just replace "Devil" with "Terrorists"
William Roper: So, now you give the Devil the benefit of law!
Sir Thomas More: Yes! What would you do? Cut a great road through the law to get after the Devil?
William Roper: Yes, I'd cut down every law in England to do that!
Sir Thomas More: Oh? And when the last law was down, and the Devil turned 'round on you, where would you hide, Roper, the laws all being flat? This country is planted thick with laws, from coast to coast, Man's laws, not God's! And if you cut them down, and you're just the man to do it, do you really think you could stand upright in the winds that would blow then? Yes, I'd give the Devil benefit of law, for my own safety's sake!
