If the United States Government LIED about this, we'd be allowing Terrorist Attacks on our soil. I hate to say this, there will be more of a risk of attacks now since we killed Bin Ladin. I do not think they will happen, (and nor do I want them to happen). But I do think there will be more attempted attacks. The radicals are going to say "They killed our leader, let's kill them"
I agree that if Bin Ladin was NOT killed, he'd already have a video out saying "HAHAHA Stupid Americans, I'm still around". As for dumping his body in the sea. I agree on this. We don't want that on our homeland. Some idiot/extremist would try and find it. And I would not like having the fact, we buried the man who killed thousands on 9/11 on OUR SOIL. And not only our citizens, but our troops as well.
I'm not a Obama support, but I'm giving him ALOT of credit right now. He's done an exceptional job on handling this. I give credit towards George. W, Obama, and the United States Military for this.
