I know he's a terrorist and I wouldn't want to fly on a plane with him.
No you don't know that. There is no clear evidence he threw the grenade that killed Speer and even if he did, if using a grenade in a firefight makes you a terrorist then there are a shitload of soldiers around the world who are now terrorists. And then of course there was that 10 years in Gitmo during which he was tortured into making a confession. If you don't want to fly on a plane with him then stay home or catch a different flight.
