People quiver in fear of having too many "foreign parts" in their rifles, even though I cant find a single case of someone being busted for a 922(r) violation. (how do they check anways? I've never seen BATFE doing parts count inspections at the local ranges..)
People are too busy paying their mortgage, and worrying about the 30% interest on their 5-digit credit card debt. They're too busy watching "america's favorite past time" on tee-vee, never mind actually playing it. They steadily ignore the 50% decline of the US dollar in recent years and the 9 trillion dollar debt along with the 200B per year we funnel into Iraq. As long as the bread and circuses continue, the status quo shall be maintained.
You may be right in that this is true about 95% of the population, but, as Texasskyhawk mentions, there ARE a fair number of people, many of whom are armed, organized, and motivated, to whom it DOESNT apply, and whose to say if all those groups the feds were worried about with a "bad" Heller ruling started shooting, it wouldnt spread fairly quickly to others? I'm inclined to thing that if 1 or 2 "millitias" and 20+ states decided to start shooting, it would snowball pretty quickly, and things would get pretty serious, fairly quick, with people having to choose a side. Now, I'll agree that most of that original 95% would stay on the governments side (or be neutral), many people WOULD join the millitias and would now be inclined to act as part of the group, when they wouldnt have as an individual.
So, now theres a lot of millita people shooting it out with the government, so likely NG and regular troops get called in to help. How many would be inclined to fire on American's, on american soil? Some would, some wouldnt. Some of those who wouldnt would just do nothing, others may not take kindly to seeing fellow soldiers firing on Americans, and may fire on THOSE soldiers to stop it. Not the shooting has spread to cause a split in the military, even if a relatively small one. So now its not just a bunch of "wanna-be's" vs cops and soldiers, now there are some well trained, heavily armed soldier involved in the fighting aginst the government, and it just sreads, and spreads, and spreads......
Certainly a possibility. It doesnt have to start with a mass uprising of gun owners. It could start with just a few hundred or so "extremeist" millitia goups, and spiral out from their.
