The latest NSA contoversy

Should we be concerned that the NSA has obtained phone records about calls made in this country by millions of innocent Americans? I'm not sure... it doesn't bother me, but I understand why others are.

However, it does seem clear that what the NSA did was not illegal, that it violated neither FISA nor the Fourth Amendment (see this article). So the usual suspects who are throwing fits of hysteria need to chill a bit.
