Current gun laws in many states facilitate gangs, criminals, terrorists, the mentally unfit to buy guns legally or at least without much effort. And since it is easy to cross state boarders without issue unless you are an idiot, everyone. Why would responsible gun owners allow this? The only true risk to gun ownership for responsible citizens is the continued allowance of those that should not have guns to have easy access. So lets take a poll of who benefits from printed guns. Not gun manufacturers, why buy a gun if you can print one. Not law abiding citizens, they can buy a gun pretty much the next day or two. Pretty much all those that should never have a gun benefit from this.
