The only part of Fast and Furious that was botched is that it was uncovered. Otherwise it was working perfectly according to plan. The goal was to have firearms that were sold at U.S. gun stores show up at Mexican crime scenes. Then Obama would have had the "evidence" needed to renew the national assault weapons ban.
Partly my take also.
And that is where it makes their little plan even more egregious. They planned to cause mayhem and even murder in Mexico and along the border. It had to be severe enough to convince Americans that we needed tighter gun control laws. That is called premeditated murder by most standards.
