I've spoken with a few police officers about the whole gun confiscation thing, and all of them said they wouldn't do it. If ordered by their superior to go house to house taking guns, they would quit, and probably fight for their own right to keep their guns. Think about it--Granite and others have already brought up that trying to take someone's guns away is practically a death sentence. Would you like to go house to house forcefully demanding that gun owners hand you their guns? No, thank you.
A few may actually give up their job over something like this but not many.
If it happens, there will be a grace period people will have to turn over their weapons, after that, any one that is still in possession of a weapon will be in violation of the law.
Once the grace period is over, if law enforcement learns of illegal weapons are being held by citizens then the officers will take what ever action the law requires.
Each individual will need to decide if keeping illegal weapons is worth loosing personal freedom (jail time) over, those that have families and or other responsibilities will not risk loosing everything they have in order to keep their weapons. They will make the trade off, the right to bear arms in order to stay out of jail and continue with their lives!
For those that decide to retain their weapons, they will be weeded out over time by law enforcement and or the military.
IF, the Constitutional Right to bear arms is over thrown by our government, the only hope of turning it around would be an armed revolution.
I'm not sure there are enough people left in this country willing to risk everything to stop a gun ban once the ball gets rolling!
People are sheeple!
If you really believe in the right to bear arms..now is the time to do something...write your representatives and any one you can think of and tell them, go to town hall meetings, go to rally's and marches, let the government at all levels know of your decision!
