Clintonflunky Leon Panetta is the logical choice for fall guy here. He was previously turtled to the position of CIA director, where he could have been easily plinked off if anything had gone wrong, like the bin Laden hit.
Although Panetta has had a long and broad career in public service, it seems to have been lived in reverse from early merit in the Army and then the Republican party, to centrism (a hash of disconnected views) to Democrat party to Clinton inner circle where up is down.
Panetta is an empty vessel who unearned his post long ago. He may now regarded as useful.
Panetta has a long leftist history dutifully ignored by many.
