Yeah the moment the French royalty were fucked in the French Revolution was when the soldiers sent to stop the March to Versailles joined the peasants. When the police/nasty girls/military are sent to stop peaceful protesters and they decide to actually join them, then the state will have lost control.
I still think the libs and dems put way too much stock in some general military response to something like this. I can't imagine the grunts of the military are more likely to shoot conservative protesters than politicians. But what do I know.
