I want to say that I know that the Bush admin used the same type of plan but did inform the Mexican govt about what it had planned to do. I feel that Holder, in an attempt to show it was too easy to get automatic guns to criminals and the drug cartels, set out to try and start serious discussions about the limiting of the 2nd amendment. By showing how easy it was for automatic weapons to get from the US to mexico, the Obama admin could try and clamp down on automatic weapons. It's just a theory. Feel free to shoot is down.
