- better make sure that they are locked up really good and nobody but YOU have access to them. If you have a family member that gets easily unhinged, then you will be accountable if they get access to your guns and use it to kill others, including you or themselves.
I'm appalled at people who know that they live with someone who has a short fuse or mental deficits but still knowingly own a gun. I don't know if they bought a gun to protect themself from the mentally unstable person or what, but it's very irresponsible since that person has a tendency to snap.
