I don’t know why you act like taking old, crappy guns out of circulation isn’t meaningful. Just because assault rifles are involved in the biggest and most horrific shootings doesn’t mean that no harm is done with more mundane weapons. It seems plausible to me that old shitty guns are the very ones that kids find lying about the garage, or that get sold under the table to who knows what criminal, or that misfire and injure someone during legit usage.
