>I've been fingerprinted.

That is a basic requirement of being a cop.

>I will soon be getting a passport, for the first time, and I see they want me to tell them who I am. Now, that is an invasion of my privacy, isn't it?

No it is not an invasion of privacy, just requirement to get the device that identifies you when crossing borders.

>I think everyone who enters or leaves our country should give DNA samples, so they can be identified, if/when necessary.

Arrh, so we are all guilty until proven innocent, I thought it was the other way round, I always had a sneaking suspicion that that is how the police viewed the general public.

Anyway it is just another step toward "Big Brother"
