Identity Checks at US Airports

As most people know if you live outside the US you now have to (basically) apply for a visa and get your photo and fingerprints taken, in the name of fighting the "war on terror" (I'm gonna refuse to use caps on that from now on!). What a lot of people probably don't know (especially if your not from/in the States) is that there is a court case currently going on that is challenging the idea that presenting identification papers has any effect on terrorists carrying weapons. I picked this press release off the EFF, which says that

the Electronic Frontier Foundation filed a friend-of-the-court brief on behalf of the plaintiff, arguing that compulsory ID checks at airports violate the Fourth Amendment.

So it appears that the US Government isn't just paranoid about "aliens" but also their own citizens, and that there is someone who has a problem with that.
