...only one of the five people killed in the raid was carrying a weapon and firing. The detail seemed at first to diverge from White House accounts claiming the Navy SEALs encountered resistance throughout the raid and were engaged in a firefight during much of the 40-minute operation. ...Another U.S. official said there were "at least a half-dozen weapons" found at the compound. The first person the SEALs encountered at the guest house "immediately opened fire" before being killed
So one guy held off the 24 SEALs for 40 minutes despite having been killed almost immediately. There it is, crystal clear.
Bin Laden was armed with his 36 D caliber wife, which he threw at the SEALs forcing them to shoot in self defense.
