Trust me, they did indeed drop that letter like a hot potato, would you want something like that going in front of jury?
All your shoelace belong to us!
I also recall someone tried to register paperclips (as MG conversion devices prior to May 1986) for various open bolt semi-autos, not only did ATF refuse his paperwork, they showed up at his shop. Ransacked the place and confiscated every paperclip in his building, made plenty of threats and left. Surely I'm not the only one who read this story almost a decade ago, might jar some of your memories on who posted it.
