Fast and Furious: for conspiracy theorists who find birtherism has gotten boring

Five Signs You May Be A Fast & Furious Conspiracy Theorist

One of the ways of identifying and debunking a conspiracy theory is identifying what must be believed in order to accept the conspiracy theory. TPM identified five things Fast and Furious believers must believe to conclude the Obama administration let Mexican gangs have guns in order to gin up support for gun control in America. I find these to be the strongest two:

1.) That the Obama administration wanted to spend political capital on gun issues. When Fast and Furious started in 2009, the Obama administration was not talking about guns. There's been little movement on the issue of guns their whole time in office - even after a member of Congress was shot - and the administration has in fact expanded gun rights in national parks and on Amtrak trains. The idea that they'd even want to touch the issue, or even thought that they could make any progress on it is simply not supported by the available facts.
...
3.) That the number of weapons going to Mexico wasn't already sufficient enough. Plenty of weapons from the U.S. were headed to Mexico before Fast and Furious got underway in 2009. In fact, more weapons were recovered at crime scenes in Mexico before Fast and Furious got underway than after it had been going on for awhile. As Holder told Congress, Fast and Furious was "a flawed response to, not the cause of, the flow of illegal guns from the United States into Mexico." In short, the few thousands weapons sent across the border as part of the program are a fraction of the total number of American firearms that end up as part of Mexico's drug war.

I'll add one more: you have to believe that Americans would rally to gun control because of more killings in Mexico when they won't after tens of thousands of Americans are killed with guns every year, year after year.
