Yep, but it is good press for them and makes them look like they care about the children, when in reality all they are doing is trying to advance gun control.
Sure, some people will vote for whatever because they truly believe they are saving children, and with good reason, but they won't look at the big picture and understand they are being duped into some legislation that will have no affect on things like this.
jmorris asked if they stole a truck and ran someone down with it would they hold the truck or the person liable. Of course they won't, it doesn't help their anti gun cause.
Do the antis get up in arms about other things that kill far more kids than guns? No, they don't, because they are not trying to save kids, just take your guns.
That said, a lot of otherwise pro gun people will say leaving a gun in a place where it is easy to steal is at least being careless, or even negligent, or worse, should the owner should be held liable for. Just think about what the average person out there will think. Not good.
It is bad press for us and one that is hard to refute/defend/debate/etc. Just bad all around. We'll just take our lumps on this one, and they know it.
They have no qualms about writing it the way they do, blaming an inanimate object, since their sideline purpose here is to teach people to fear guns. That part we can defend and debate, it's just a matter of better educating fence sitters and the general public in general.
