Not saying im a conspiracist, or that this is true, but it makes sense. Yesterday a U.S. Chopper was shot down killing 31 Military dudes in afghanistan. MOST of the Navy Seals that killed Bin laden got killed in the crash....
I saw on BBC News earlier that none of the Navy Seals who actually killed Osama were on the helicopter, it was just guys from their unit. Although not sure how reliable the BBC's source was, it was pretty soon after the crash when they said this. And to be honest, they're in the middle of a warzone, in one of the most dangerous parts of that warzone. It really isn't that odd that a helicopter was shot down, the Taliban just got lucky in that the one they got had a lot of people on it, who happened to be affiliated to people who carried out one of the historic acts of the early 21st century.
