Laura Rozen raises the point I've touched in a few times - if there are thousands (between 4 and 20 thousand are estimates I've seen) of people with direct links to al qaeda wouldn't we have arrested a few? Sure, there were the guys who wanted to take blow torches to the Brooklyn Bridge but even their arrests happened using actual warrants.
It's pretty much established that they know fully well that most or all of these people are not terrorists and that they have no intentions of committing terrroists acts. So we're spying on innocent people on the off chance we might learn something.
Look over there! Cameras in England!
