Another Reason to Have Fewer Guns, Because Fewer Guns Equate to Fewer Crimes with Guns

This gun started out as legal.  Someone who bought it legally was careless in not researching who they traded it to or to whom they sold it. That legal buyer didn't care about anyone else who might end up on the wrong side of that gun, a victim of gun violence or the threat of gun violence.
It is this lack of care, this problem with legal guns becoming illegal guns, that proves our so-called law abiding gun owners aren't really very good about preventing their firearms from ending up in the hands of criminals.  Because they do not take the care and are not as responsible as they need to be voluntarily, we need regulation to penalize them for those deficiencies that harm us all.
We need the gun nuts to have some skin in the game, to have something on the line for what happens with their legal firearms when they become illegal firearms.
I favor regulation, licensing, and some form of bonding where they lose money if they transfer their legal firearm to a prohibited person, or if their firearm is used in the commission of a crime.
