One thing I think needs to be stressed into everyone's heads though is that if there ever comes a time of open revolt by the people against its government, certain conditions MUST be adhered to.
First, who is your target? You cannot just openly shoot anything that works for "the man". For example, local police belong to the city/county law enforcement. Are you rebelling against them? No. You will likely be rebelling against the federal government. You must make your intentions clear that your enemy is who you pick and stick to it, unless attacked without provocation from another party. If you start shooting everyone in sight, you will be labeled a terrorist.
Second, you must communicate with the people all the time and make sure they understand exactly why you are rebelling and whom you are rebelling against. Explain to them that your militia or group will not in way, shape or form attack the innocent or those who want nothing to do with the rebellion, and stand by your word. You can, of course, express that donations of food, water, shelter, clothing, etc. will always be gratefully accepted.
Third, ensure your militia or group is properly labeled as a group rebelling against the government and not as terrorists. At every point that people attempt to label you a terrorist, always counter them stating they are wrong. The best way to go about this is by passively asserting yourselves by wearing uniforms and having a flag. Ensure your uniforms are easily recognizable and that your flag could not be mistaken for anything else.
Finally, instill in your men that you fight on the side of righteousness and for the greater good, even when many others will denounce you at every opportunity. Always display confidence in achieving your goals and make sure the people see you for who you really are...respectful, kind, and well-mannered toward the public and that same public knows who the opponent is. People will decide for themselves which side they choose to support, and with any luck, you will have a majority of them with you.
