I've been saying that for years. It's not like criminals can't get guns anyway.
I’ll take the argument even further.
Let’s just say I wave my magic wand and all guns suddenly go away.
In this day and age, it’s a piece of cake to make your own weapons. And who are going to be more motivated to do just that? Criminals.
And then what recourse would law-abiding citizens have to defend themselves? Nothing.
