If you're the head of the ATF and oversee a botched gun sell operation to Mexican cartels, shouldnt you resign?

The agents them self testified that the orders came from above their bosses head. The AFT were simply following orders to let those weapons go. I wonder who does the AFT answer too? Couldn't be an old Obama buddy, could it? At least some more of the pieces are falling into place about why the border isn't seriously being protected.
