...a self-described "anti-gun woman legislator" writes to me as an expert, for the fifth time, asking, "You still haven't explained to me why anyone needs a gun that shoots multiple bullets in a few seconds."

[gun control] is still being promoted, yes promoted, by a twisted "news" media, once again promoting its decades-old agenda to curtail America's unique civil right to arms*, using tragedy as the motivator...

devastating human loss isn't the issue, and neither is unspeakable tragedy. You are concerned with how many bullets because that's what you are being told to care about...

You ask about the need for such guns. This is hard for a lot of people. Piers brags that he doesn't get it. Are you ready? In a free country like ours, ownership of property is not based on need.
