Look at Iraq for the past 10+ years. There are tens of thousands of veterans home now who have first-hand knowledge of insurgencies. Some will fall on both sides of this issue. If the gun-grabbing fascists push (and it looks like they are of a mind to try it) then I expect we'll see the same kinds of ambushes and other mayhem here, in America, that we've seen in Iraq.
It's not the lone guy hold up in his house yelling "Molon Labe!" at the police outside that lawmakers, swat, and others need to fear. It is the dozens of guys that aren't even on their radar yet... The guys that are doing intel work, recon, and tracking them to where they live... It would be a huge, devastating mistake for the gun-grabbers to think that the pro freedom, pro Constitution forces would be isolated and fighting only a defensive battle. I mention this only because I want them thinking just how ugly this could get. Don't push the patriots.
The tipping point comes when people just start 'taking out the trash' as opportunities arise.
If FreeRepublic.com is not shut down before we get to that point, I'm going to be really interested in where this forum eventually lines up.
