The one before the registry was good enough.
First, as far as what I'm hearing from gun owners, it isn't as simple as you think. And if is was, I still don't see how would a person who registers his weapon not be capable of shooting someone.
Aren't people obliged to register their guns? And even if a gun goes to the wrong hand, how does the gun registry make any difference?
You have two scenarios: one, no gun registry, a gun is stolen and used in a crime. The second, we have a gun registry, a gun is stolen and used in a crime. What is the difference? None, except that in the second scenario, if the guy didn't know the gun was stolen, he may go to jail for that crime. There is something in common however: the crime won't be prevented.
Once again, homicides are increasing.
Here is a possible solution. The majority of shootings are gang related. What are they mostly interested in? Drugs. Don't you think if we legalized it, there'd be less gangs and hence less shootings?
