What about these guys walking around outside Presidential events with semi-automatic weapons? In the media, I keep hearing that they are "exercising their Second Amendment Rights...foolishly, maybe...," but that's what the talking heads are saying that they are doing.
Why now? Do you really think they could have got away with that during the Bush administration? Every one of them would have been taken down and disarmed and somehow hauled off as a potential threat. Remember how protesters were kept away from any Presidential event? They were only making noise. So...why now?
Think about what would happen if somebody tried to arrest them, or remove them from the vicinity. Would they become (more) threatening; would the situation escalate? I don't think so. I think they would allow themselves to be hauled off. Of course, within minutes, the NRA would be there, armed with lawyers and the Constitution, looking--nay, begging--for trouble.
In one fell swoop, the public would be thoroughly distracted from the issue of health care reform, and the President would be fighting two battles; one that's a hell of a fight, and the other that is unwinnable.
And the voice of the majority would be silenced. The rule of Lobby would be out in the open and democracy would be dead.
