So if passing laws doesn't prevent people from committing crimes, let's get rid of all of them.
Passing new laws doesn't stop people from committing murder, so let's get rid of the laws against murder.
Passing new laws doesn't stop people from diddling little kids, so let's get rid of those laws, too.
Passing new laws doesn't stop people from driving drunk, so let's get rid of those.
And if all of that sounds batshit crazy, then I would submit that all you gun nuts should reconsider your arguments.
