These are hopefully a step towards a safer life. So what if its a "police-state", i'd rather be safe in my country! Its not fun living in a place where theres a lot of threats.
And i also agree that if youve got nothin to hide you shouldn't be bothered. It's paid for one way or another, taxes, out of our pockets etc as mr_odwin said.
Do we know for a fact that the ID system could have prevented this, perhaps the police there are just not up to scratch? (i am not saying they are, just you can't assume faults, without knowing how and why it happened)
And also, a very small point, ID can be used to prove you are the age you are, as im sure many people like me have problems when trying to buy age restricted items or going to see a film.
