Indeed. Security forces are on alert, and it's going to be a bit twitchy for awhile. OBL's much more an inspirational martyr at this point, and we could all do with a little less inspiration. On the other hand, as Keith points out (http://foknewschannel.com/bin-laden-dead/):

The President is right to raise security levels at US installations and bases. However, remember the premise of Al-Qaeda is the long-planned, meticulously-choreographed “spectacular.” While an attempt at vengeance should not be discounted, it should be pointed out that what we would call in normal-human speak ‘a quick turnaround’ is not their forte. A terrorist in a hurry is a terrorist who drops the backpack bomb when he gets chased out of the subway. A terrorist in a hurry is a terrorist who lights himself and not his underwear bomb on fire. A terrorist in a hurry is a terrorist who locks his house keys in his car-bomb in Times Square.
