Proof of what a national ID service is good for.

@Ronin And if you are suspect of a crime, police is sure you did it but they can't proof it, no thx. Prosecuters tend to 'make' a case. Plenty examples of that.

zero reported cases of such a thing happening over here don´t give me cause for alarm....there have been a couple of cases of interrogations getting kinda "heated" let's say...but nothing as clever and sophisticated as you are suggesting.
on the other hand look at the number of prisoners in the united states being cleared while they are sitting in death row....and they don´t have ID cards.
If a state wants to **** you over I hardly thing the existence or not of a small card with some bio data is the thing that is gonna make a difference.
