Fine but there's always the possibility he hits the lotto on the first attempt. But you hadn't even considered the effort to brute force a 3-digit 0-50 combo lock until I pointed it out did you?
Lame excuses do not absolve one of this responsibility.
If you weren't so obsessed with insulting anyone whose comments either do not mirror your own position, or satisfy your ego you would recognize that having guns in a safe will only slow down a person determined to get them.
Far from not even considering it, I read Richard Feynman and he was something of an expert at it.
If she felt her gun safe was not in a secure location where he could not work at it until he opened it - then she needed to move it to a secure location - or store her firearms elsewhere.
If you have guns (and I do) you have a responsibility to keep them away from someone psychotic enough that you think they need professional help.
Lame excuses do not absolve one of this responsibility.
I don’t see how pointing that out is an insult. It is a fact. Lame excuses never absolve one of ANY responsibility in life.
