ATF declares a 14 inch shoe string a machinegun http://www.jpfo.org/shoestring.jpg Here's a picture. Note the attached metal tab where the C2 inscribed the serial number on this "machine gun".
I don't think that's right . . . most if not all semi-autos have a disconnector so that pulling the trigger won't fire the gun unless the bolt IS closed. It would take some sort of malfunction (wear, broken part, etc.) to fire the gun in an out-of-battery condition by means of a trigger pull.
OK, here is the previous ATF agent after he got out of the shower and before he got dressed in Quigley's post......
I wanted to post this story, but decided to do a search on it thinking it might have already been posted. Anyways. Just a reminder and a bump
