The "Fast and Furious" gun-walking operation was to make it look like guns were being bought in the U.S. and making their way across the border into cartel hands for the sole purpose of saying "Hey look at all these American guns that made it into Mexico. We must act quickly to ban guns." Impeach Obama Now! New Fast and Furious docs released by White House http://www.cbsnews.com/8301-31727_162-20114184-10391695.html
To be honest, no documents have yet shown that the WH was informed on the 'walking' part of operation. I'll eat my keyboard if it's proven they didn't actually know but....so far those communications have not yet been released.
