I have a Medal of Honor book.
Many times, when you win the nation's highest award, you're completely pulled from the fight. Or at least sidelined for a year or two.
Lets see...Bin Laden was supposedly killed and within hours buried at sea with no proof of his death and now the only people that were actually there to witness the death of Bin Laden were killed 6 weeks later.
Sounds like this is standard governmental protocol. Issue a lie, and then kill all people that could expose that lie.
