Matthew Yglesias takes on glib t-shirts proclaiming "Tyranny Response Team":

The fact of the matter is that tyranny is a serious problem, and it calls for serious solutions and serious responses. The idea that the common man is going to use small arms to fight off a modern, 21st century military organization is ridiculous. And the idea that there’s going to be widespread household ownership of the kind of anti-tank missiles and other weapons you’d need to fight such a war is also absurd. In the real world, people stand up to tyranny with nonviolent tactics of civil disobedience that let protestors fight for the loyalty of the security services’ rank and file.

Matt is absolutely right in any case where the nation's citizens are being attacked by their own army, invading armies have more difficulty because they are only projecting a small portion of their forces in a hostile nation.  Even then, the citizens need serious help from some arms dealers to be able to put up the fight.  Iraq was loaded with AK-47s, and yet Saddam Hussein stayed in power until the US arrived.
