If you have a person of questionable mental health living with you you may want to keep your guns locked away in a quality safe. Lanza’s mother had one of those el cheapo sheet metal safes but may have kept it locked since it was not broken into. It may not completely prevent a motivated person getting into it but it can’t hurt.
