What I find kind of funny is that people are willing to destroy their firearms or go to jail to protect them from being stolen by a criminal. If they are stolen your insurance will most likely pay for them to be replaced. If they are destroyed by a "trap device" then I doubt seriously the insurance would pay, especially if said device is illegal. If you go to jail (assuming you would - see the next paragraph) you can't legally own them anyway so either they get seized or you give them away.
What I don't know about this situation is the penalty if this trap gun killed a criminal that was trying to break into the case. While owning the trap gun is a misdemeanor, if it kills someone who isn't supposed to be there anyway (and you could legally shoot) how is that viewed?
It would have been cheaper to buy a real safe plus it just goes to show how the lack of common sence sometimes can cost you your life.
