It would be incredibly foolish to walk into a business masked. I don't care if you're in Nome, Alaska. I'm going to react badly if I'm in there when someone does that. I hope that most other CCW holders would too. Not as in gun them down on the spot, but I might draw my weapon, almost certainly if it's more than one person. There are some things you just don't do, and that's one.
I prefer dangerous freedom over peaceful slavery.-Thomas Jefferson
I would rather die on my feet than live on my knees.-Euripides
