Constitution wise no Military person has the authority to shoot or injure an American citizen no matter who the commander in chief is or what he or any other elected tells them to do. This is why you never see the military involved in any riots or citizen affairs. On every occasion I can remember National Guard people were used for riot control such as the black riots in the 60s. The one occasion I did see illegal use was when JFK used the 101st to escort the first black students to school after the courts finally committed or completed the true end of the civil war, but all our Presidents are over stepping their authority simply because it benefits them in some way. In the future I think if the military would take up arms against citizens they would be put down by state militia and citizens. It will never happen because we will always have someone high in the ranks that would refuse to order his command to do so. On the other hand a good example of overstepping authority was the Waco incident where they did use personnel and even a Tank to burn women and children to death and of course a democrat a-hole the perv himself was in charge or his man-woman AG.
That was one time those responsible should have been charged with murder, but the youth of today have no knowledge because they do not teach history nor do they broadcast any anniversary of a pure and simple slaughter of innocent people. They got their ass shot up because they illegally entered their domain without a proper warrant, the warrant was an arrest warrant for 1 individual that could have and should have been served on the one individual while he was running each and every morning which they knew beforehand, they wanted to go around the warrant and get inside. I am glad they shot the hell out of that bunch of jack booted thugs that were brought in from out side the state, every time I see them rolling off that roof I smile. After this was over with and all burned alive the congress and senate were all standing around slapping each other on the back laughing and even giggling on open mike. I hate democrats to the core, they are what we see today and it will get worse but I don't believe they will attempt to use the military because they would most likely become the ones under the gun. Until the citizen brings the pay down for a congressman or woman and the senate to status of a working person, then we would see people who want to do something for America, not get rich which is what all these people are doing today.
