'Now, I am very much against any "police state", but walking around ANYWHERE without ANY ID is just stunned'

I beg your pardon???

I have never in my life made any effort (or had the need) to carry identification at all time and have never been asked to produce any (except when cashing cheques, crossing borders and that sort of obvious thing). Any place where police can whisk you off the street for the sole reason of NOT having ID on you would seem uncomfortable to me.
