It doesn’t matter if “gun control” [sic] actually prevents murder. That’s the wrong question, because no one has the “right” to forbid others from owning and carrying guns. That “right” can’t exist and cannot be created.
This bothers a lot of anti-liberty bigots. So they keep focusing on the wrong question– and I suspect lying about the data in order to get others to come to agree with their conclusions. But, either way, it really doesn’t matter.
