ckurts, I read the same article by Mas that you did.
Just a thought on this, MAYBE he was denied a CWL and he figures that if he adverizes that he's carrying when in reality he isn't it might make some BGs think twice about attacking him. After all, states with shall-issue laws usually see a decrease in violent crime over other states because BGs don't know who might be armed. So, there might be some merit to it.
Of course, I personally wouldn't do it because I would be afraid that while it might discourage most BGs, it might encourage a few others.
