Fist off, I have no plans to hand over any weapons that may be in my possesion. But just for the sake of knowing how the "bring lots of body bags" crowd plans to fill the bags, I'll bite on this one.
Let us assume that the guys who show up at your door to take your guns aren't going to be local cops in uniform at 5:00pm. I don't think the U.S. armed forces(well, maybe some National Guard guys) will turn on the population, so we'll leave them out of it as well(including spec. ops). What if it were Nato troops that were trained by the Federal Gov. & backed by the U.N. ? May be they would be smart enough to generate regional lists of target homes or sites by what they deemed your risk factor to be. Would it be possible that one night a shape charge could blow a hole in the side of your house & the next thing you know there would be flash bangs going off in your bedroom ? What if they used tear gas, do you sleep in your gas mask ? If they were to fill your heating ducts(if you have them) with gas before they even come in, would you just wake up in jail or the back of a black van ? What if they just came to your work dressed as a guest of the company & walked up behind you before knocking your butt out ? The list of ways to "grab" you if they want you is endless. It was said that if 20% of the people were armed against the gov. that it would fall to a revolution. I'm not sure that would be the case if they were to go about it in the right way. With enough intel, there could be a decent list of gun owners put together in this country. If you are on the list & don't hand over your weapons, becoming a criminal, are you ready to flee to the hills. What if you were not able to buy, sell, hold a job or even enroll your children in school if you made "the list". Sure, many of us are ready to do that today, but if you are on the "red list" & get grabbed in the first round up, you probably wouldn't even see it coming. My point here is that unless were are aware that we will be attacked, where & when, we stand little chance as an idividual to defend our property against an effective & informed force. Do you realy think for example, that if the Delta guys or a seal team wanted your guns they would need body bags ? I have a hard time thinking many of us(if any) are ready or even understand what it would take to get off just one round on those guys. I agree that we should do what we can to protect our rights, but if the gov. is smart, they will not allow us the time to form organized & armed groups. Knowing how many of us own weapons, I would think they will try to cover that angle. Maybe I'm wrong, but since this is all just a what if this or that happened thread, it doesn't realy matter.
