That being said: if it ever comes down to gun confiscation, I doubt it would be on a house-by-house basis. There are just too many houses to search. Instead, we'd probably see roving sweeps of dangerous neighborhoods, road checkpoints, and massive deployments of metal detectors in public places. There are undoubtedly already lists containing the names of potential troublemakers on a Zip-Code-by-Zip-Code basis (PROTIP: If you are a member of Free Republic, you're on the list) who would be detained in advance of a gun ban. My guess is that most gun owners would have prepared a hidey-hole or two off-premises for just such an event. It won't save them from being arrested (if you've ever had a firearm in your house, the Dog will know), but at least Old Betsy will be there when you leave police custody. If you ever do...
I'm not worried about it, myself. Worry is pointless. I intend to do what I have to in order to keep my family and myself alive, and I trust that the good Lord will continue to arrange things so that everything turns out all right for Family Chan in the end. (Some people call this "luck"; we Christians know better.) Someday, when my time comes, the Lord will remove His protective Hand from ol' B-chan and the Enemy will kill me off (hopefully, after an epic battle!) but I trust that God will bring me back in a new, improved version on the Last Day.
With that in mind, I'm going to just keep getting up every morning and doing my best, and I heartily recommend the same course of action to you.
