As a Mechanic of sorts for some fifty years I also have noticed that wrenches, scanners, and tire machines are not magical. They all were designed by somone to fill a percieved human need. I regard guns in the same way. If people didn't want, need, or buy the tools nobody would make them.
Guns are merely a tool for keeping the peace, no more evil than the 1/2" ratchet wrench, (a tool for tightening certain specialized fasteners called nuts and bolts) which our society depends on.
Personally, I suspect that more innocent persons have been killed, injured, or seriously inconvienienced by the inappropriate use of wrenches than were ever inconvienienced by the use of a weapon in civilian hands.
Ban all wrenches
