I take the view that having a gun carries responsibility with it. If it's lost, it's not a purse, it's not a pair of sunglasses. We all know what it's capable of, especially in the wrong hands. So I do believe we as gun owners have to be more vigilant, be it in a house with kids, or a vehicle. Leaving a gun in an unlocked car, as far as I'm concerned, is negligent. Compound it by leaving it in a spot where it's visible, and I think you're almost to the point of criminal negligence.
This is not the same era of 40 years ago, where in certain areas you could keep a rifle in a truck, hanging on your rear window, and nobody touched it. It's a different age and we have to act differently, too. Things are happening every day, we see it on the news, and we're certainly not helping ourselves by feeding into it. The person doing the act is the criminal, but we shouldn't be the enabler.
