Is Obama Clueless or Blameful? - You Decide!

Pres. Obama has now claims that he didn't inform Mexico of US gun smuggling across the border under an op known as “Operation Fast and Furious” because.... um, he didn't know about it.  When asked whether he knew of the weapon smuggling plan, Obama responded that it is - are you sitting down? - “a pretty big government” with “a lot of moving parts.”

 I'm looking for an a-- to blame that isn't mine!
