Except responsible gun owners wouldn’t buy their child a gun and give them access to it whenever they please. Any firearms I may or may not possess would be locked in a safe which no one but any spouse I may hypothetically have had access to. Unfortunately I lost all my firearms in a tragic boating accident a few years back.
What I’m trying to say is that, while the government shouldn’t be allowed to come check that people have their guns locked up when not in use, there should absolutely be repercussions for anyone found to not be doing so.
