Well, this puts the lie to a few theories I saw floated as an excuse for the Maryland ban: a) it was necessary to allow the military surveillance plane to detect a "muzzle flash," and b) the poor, overworked, and apparently clueless MD police were running themselves ragged responding to reports of gunshots, by hunters.
For some reason, Virginia doesn't (yet) have similar problems. (sarcasm/off)
BTW, the media reported hysterically last week that one of those hunter gunshot incidents was the result of a car window being blown out by hunter buckshot. I just read that the driver broke the window himself, and is being prosecuted for making a false report.
