That's fair, sometimes it can turn people off, I can believe that such graphic warnings could reduce gun ownership overall if applied to gun packaging.

Do you think that the Texas school shooter who inspired this HN post would have been deterred from purchasing and using his gun to kill children if he had seen graphic warning labels on the packaging of his gun?

Uh no, I'm just saying license and registration is irrelevant to the question of whether "We need gory pictures from the executed kids everywhere". We already have license and registration requirements for cars, but if stopping gory deaths is my motivation then license and registration requirements would not be enough to placate me, it would effectively be a call for tougher restrictions, so I decided to focus on the tougher restrictions on cars that was suggested (eg related to drunk driving).
