What did O know, when did he know it, and why did he do it?

Just a thumb in America's eye?

Apparently B was known to be a deserter and a convert, and was suspected of having intended to become a turncoat and in the most literal sense a traitor, joining the enemy to fight with them against us.

So why did O trade five dedicated terrorists from Gitmo for him?

And why the White House fete?

Yesterday, the army charged B with desertion and "misbehavior before the enemy."

In his effort to empty the Gitmo detainee facility, the president traded five hard-core terrorists for a man who now stands officially accused of abandoning his fellow soldiers. 

He very may well be court-martialed and spend a good deal of his life behind bars. 

It’s the Taliban 5 who, beginning in just a few short weeks, get to live happily ever after. 

WSJ says O knew the worst that day in the Rose Garden.
