@Lustig Andrei,
This is actually a very well thought out question and very clever. I hope I answer in a way that expresses my view without trying to clearly side with one.
If this process comes down, most likely, as it is currently happening, we'll see the laws and new restrictions pass, most likely due to executive orders. Shortly after and through the 10th amendment, the people will get the gun control bans repealed and then some new measure without much in it come through and pass. With the new laws to be what our new gun control will be, but probably just leaves law-abiding citizens still cursing.
The other side I can see happening with current actions on all sides. This would be the most extreme by far. With the president using Executive orders to enforce gun control measures that he deems necessary. Many county sheriffs have already stated that they won't enforce these laws, which might push the President to try and enforce the laws himself (utilizing the Military or other Federal Agencies), which in response the Sheriffs would activate National Guard units, which could lead to he second American Civil War (just the same reason the first happened).
Those are the only 2 options I really see happening. Obviously I most likely expect the first happen, but with all the posturing and preparing for all the legislation going on, then maybe if all else fails to work the way it should, then the second could possibly happen; otherwise, I don't see much else happening. I feel that the biggest thing is the media attention on this, it's just causing a lot of people to pick a side, without much compromise that is necessary to enact and pass legislation like this that affects so many people. I honestly think some good could come out of all this, if only Obama and his campaign on Gun Control would sit down and talk with people on how people really feel about it, and just discuss the new laws they want to pass and compromise til they find a solution both sides can agree on.
