They are trying to ban all paths, not merely one path.Since you don’t know what *my* “assault weapons ban” would be you’re just arguing against a strawman.It's not a logical fallacy, but simply being sensible.This has to be some kind of logical fallacy. We shouldn’t put restrictions on one type of weapon because a criminal can always find a different kind of weapon to use if they are intent on committing a crime. Even if it’s not a fallacy it’s just not a compelling argument. Yet it keeps coming up over and over.
