The Gun Control Rejoinder You Were Looking For Is Almost Certainly Here

Gun Facts - Gun Control | Facts | Debunk | Myths: "INTRODUCTION:  Gun Facts is a free e-book that debunks common myths about gun control.  It is intended as a reference guide for journalists, activists, politicians, and other people interested in restoring honesty to the debate about guns, crime, and the 2nd Amendment.

Gun Facts has 112 pages of information.  Divided into chapters based on gun control topics (assault weapons, ballistic finger printing, firearm availability, etc.), finding information is quick and easy.

Each chapter lists common gun control myths, then lists a number of documented and cited facts (with nearly 500 detailed footnotes).  Thus when a neighbor, editor or politician repeats some sound bite about firearm control policy, you can quickly find that myth then rebuke with real information."

I'm most of the way through it and this is the most comprehensive gun reference I have seen so far. It looks like it was started maybe after Columbine and it's date ranges could stand some updating but even with that it's well worth your time.
