This continues to be illogical and irrational rhetoric. Certainly the problem is complex, but not nearly as complex as you're making it out to be.If anything the argument that we can stop criminals from using the best tool possible for practicing their trade via prohibition is a silly and emotional quest for a simple fix to a complex problem. Exactly how will you get guns out of the hands of those who bent on criminal gun violence? Until you answer that, asking the law-abiding to disarm is wishful thinking at best.
Imagine how much you empower the next mass shooter if you guarantee the entire country is a gun free zone for anyone who chooses to obey the law.
Why didn't Australia turn into the wild west after regulation?
Guns are already abundant and they haven't stopped mass shooters yet, so that's a rather odd argument to use. The "good guy with a gun" is mythos, by and large.
