I don't believe laws prevent crimes, a law makes an act criminal and provides a punishment. Thus I support requiring any person who wishes to own, possess, or have in his or her custody or control a license. And any person who sells a gun to an unlicensed person to be punished by a loss of said license and the surrender of any weapons they own or possess to a licensed gun dealer sans compensation.
so what do you believe does prevent crimes. BTW, the laws aren't made to prevent, they are meant to deter and make people aware that there are consequences. Not to prevent. No where will you find that in any explanation. Deterrence has always been the rationale. It's amazing how many humans don't care about the consequences until after the fact. Oh wait, i didn't mean to that, can I have a mulligan, do-over, oops. Abortion has consequences. Seems the left don't like the consequences and want the opposing view to just shut up and go away. Interesting on how the majorityof the left can't debat any subject matter without getting into a hateful spite.
If someone is deterred from doing a crime because of the punishment the law places on that crime, it prevented the crime.
Thus a law abiding citizen who resides in a State wherein a license is required to drive a car and to own, possess or have in his or her custody or control a gun will comply with the law to avoid punishment and because law abiding citizens obey the law.
And, a law abiding citizen in a State which require a license to own, possess, etc. a gun would never sell a gun to an unlicensed person, again because they are law abiding and they want to avoid punishment.
It's really that simple. The concept does not make law abiding citizens criminals as some have suggested, it simply makes it more difficult for someone who should never own, possess, etc. a gun from getting a gun.
Is it a panacea and will it end all violent murders of innocents? Of course not. But neither do speed limits or other rules of the road prevent death, and neither does ownership of a gun protect gun owners from rape, robbery or the suicide of a loved one.
