It's recognized as a mental disorder alright.
She's talking a loaded weapon with a 30 shot clip in just about every room. Not locked away, not keeping the bullets separate from the guns, and debating not keeping the safety on. Her though is optimize response time if soemeone breaks in.
She also has 3 young kids who will be bound to find them when they are snooping around to see what Santa or the Easter bunny will bring. There's just so much that can go wrong. I can totally imagine junior finding it, showing it off to his friends after school one day, and them fooling around with it just right and someone gets shot.
No offense, but sometimes the evil twisted bad guy inside me wishes that those people get shot by intruders with their own guns that were not locked away.
