Deadly weapons should be kept in a location that can't be easily accessible by a child with depression.
Anecdotally, I was depressed at his age and my father had guns. The gun locks stopped me the first time. Before I could figure out how to get them off, my mom noticed I wasn't in a good spot and had my dad give the guns to a relative and forbade him from telling me where.
The boy in question had an official diagnosis and they kept a gun in a shoe box in the closet. Guns should never be kept anywhere within access of a child and always under some kind of lock. There are very few cases where the owner of a gun isn't largely to blame when a kid shoots himself imo.
I hated it at first but then I started to leave pocket on and click links every now and then since I figured they got revenue out of it. I don't use it often but its a shame to see it go now that I kind of like it.
