Get on the ball finding them?
Just because we are not out invaiding some country that has little or nothing to do with the attacks it doesn't mean the authorities aren't doing anything.
All four bombers from 2 weeks ago have been identified, houses have been raided, explosives recovered, documents found, (plus more I would asume).
Certainly we didn't send any planes around the country picking up the bombers relatives and taking them to anykind of political / military safehaven.
Sounds like a flame, but really it's not... I just get pissed when people say Oh, we have to get on the ball finding these people... or what are the police doing etc...
It's not as easy as that... remember it's four years (two wars) later and Osama Bin Laden is still not found!
