I keep a baseball bat by the bed and a shotgun in the corner. That's my plan on resolving a burglary. Somewhere in there it would be nice to call the police. But they are a good 15-20 minutes away and would only be coming to see if I made it out alive or not.
You should get rid of the gun or put it in a safe when you are not using it for sport. It's too dangerous to have it just in the corner. It's more likely that you or a family member will use it against yourself or someone else you love.
Yes it's mostly deaths related to suicide. With a few domestic homicides or children playing with weapons. But suicide thoughts can happen to everyone, yourself in the future perhaps, or someone you care about and where you didn't see or ignored the signs.
