I will "show" my Michigan Driver's license, even my CPL on request to an individual seller on a long gun transfer out of respect to the seller (but won't allow it to be photographed or even written down). I feel it's our way of doing what we can to help keep guns out of the hands of the wrong people. There are thousands of people in our country that intend to do us harm. I realize I.D.'s, even CPL's can be faked, but we should do our part when possible. As a seller I've only had one instance where a buyer actually appeared to get really uncomfortable when I requested I.D., as I hesitated he said forget it and took off and left. I sensed something was a little shady, or maybe he was just pissed off. Oh well.
