Agreed. But I don't think any of them expected to be tied to outright first degree murder, it's all secondary to them.
I believe the objective of Fast & Furious was that the murder rate by guns increase WITHIN the border of the United States. That way the democrats would show their crocodile tears on TV so that public opinion about guns can be manipulated so much that Obama would be forced to take some bold action against the right to bear arms in America.
Increasing the murder rate in Mexico would not be enough justification to ban guns in USA. In fact, if anything it would prove a need to secure the borders between the US and Mexico (something to Obama’s disadvantage - he’s an open borders guy).
