Yeah, that's a complete fantasy. Since in US society the riot police doesn't come around with tanks and machine guns mowing down protesters, people have created this delusionthat that if they grabbed a couple of hundred M4s they could take on a government with a full blown army, and that when the shit hit the fan that army would still choose to fight with just shields and batons. There is a clip from the January invasion where a woman is fleeing the scene crying, because of the a 'violent' response from the police. I even think she just got pepper-sprayed (can't remember exactly). When asked what was she doing there, she said she went there to start a revolution. There's a passage in a book (can't remember now either) about the Mexican revolution, where a man hopped on a donkey and left his tiny village to join the armed struggle. About 5 miles from a conflict site, he heard the boom of a cannon going off. He stopped, turned the donkey 180 degrees and went back to his village.
