Japan Fingerprint

Fingerprinting and mugshots have been put in place as a measure to deter/prevent terrorist attacks.
Am used to the fingerprinting/photo process when I enter the US but still not used to the attitude of the officers who treat you like a criminal by default. Never had any problems with the officers in Japan though.

I'm not exactly sure how fingerprinting somebody is going to stop evil intentions. If a person wants to blow him/herself up then a fingerprint is not exactly going to stop them from doing so.
I can see how it can play a part in preventing overstay - photos of overstayers can be published as soon as their permitted stay has exceeded for example.

How do you feel about having your fingerprint and photo taken when you enter a country? Had any problems so far entering the US?
I personally don't care as long as it doesn't add too much extra time when getting back in Japan after a trip.
I hold an alien registration card which means I line up with the Japanese nationals when I get in - wondering if that will change.
I like the way the word "Alien" is still used for foreigners. When I think of "Alien" I only think of one thing.
