It's past my bedtime, but I'm going to engage in a little speculation by suggesting that, while "friendly fire" might be common amongst the soldiers in Iraq, and maybe amongst police officers to a lesser extent, I'd guess that it's a pretty rare thing indeed in the FBI.. Not sayin' it couldn't have happened like that. Just sayin'.
I Googled Barry Lee Bush. Unless there are two FBI agents with that name, this same agent Bush did some testifying in a case called United States v. Usama Bin Laden in March of 2001 (pre 9/ll), under the questioning of U.S. Attorney Patrick Fitzgerald, about some papers Bush recovered from a search of a building in Kenya.
Okay, so maybe I just watched the old movie Serpico. But still. Kinda odd, isn't it? Isn't it? Or is it just past my bedtime?
