"Upon reporting to orientation, volunteers were asked if they had brought a gun. They were asked to show a carrying concealed weapon permit."
Do you need a permit for a well-trained attack dog? That seems to be an effective way of doin' business, too.
I met a pretty cool guy from Utah who brought his semi-trained attack doggies. These little guys would have licked any threat to death. He had them out on the line with him every shift.
