Uhhhh, isn't this making my point? If the gun was properly stored in a safe and the kid got to it anyway, they'd be suing the shit out the safe manufacturer. I'm assuming the dad knows that he fucked up by leaving the gun (or key) out, so suing the gun manufacturer would be pointless. I never said a thing about the gun itself, just the kid's access to it. That's your projection. As derka said, pulling a trigger is a whole hell of a lot easier than other methods.
With my clearance, I use safes and tumbler locks almost every day. Sure, certainly more expensive than any gun safe mechanism I've ever seen, but the technology isn't wildly different. After installation, there's no magical generic factory reset that can be used to bypass the lock entirely without eventually having to enter a pre-programmed combination. It's not your fucking router. Factory codes are tied to the serial number of that individual lock, not generic. So, no, they can't just "search online" to find it.
It was my understanding that it's the same for most gun safes. If gun safe manufacturers are using 123456 as their default code for a factory reset--that bypasses the need for any other code for access--they deserve to all be bankrupt in litigation.
Still waiting for the documents for a safe whose code resets (as in allows you to program a new code without knowing the old) just by removing the batteries. I think you're making shit up.
Also, which is it? Are teenagers such cyber wizzes that they can insanely easily "crack" your average gun safe like you first suggested? Or were they just able to find the hidden backup key?
You're embarrassing yourself on this one, man. Excellent derail when you and I both know the gun this kid used was, beyond the shadow of any reasonable doubt, improperly stored.
