Accidental Shooting of Younger Brother by Marine While Camping and Drinking

The Daily Mail reports

Police have arrested a 27-year-old man on suspicion of manslaughter after he accidentally shot his 17-year-old brother who idolised him.  Juab County Sheriff Alden Orme says Cameron Bryce Charlton died in the early morning shooting at Yuba Lake State Park in Utah. His 27-year-old brother, Eric Wayne Charlton, is in custody.
'His brother went into the Marine Corps, and that’s all [Cameron] wanted to do when he got older: go into the Marine Corps like his brother did,' said the boys’ grandfather, Stan Charlton.
Authorities say the brothers were camping near Yuba Reservoir with about 20 other people.
Officials say the brothers and a friend were awake and outside the tent when the gun went off and killed the teen.

I would think it's safe to assume that he was not only a lawful gun owner gone bad, but one who'd had proper training.
This is additional evidence that the gun-rights attempt to blame gun violence on criminals is bogus.  They themselves are often directly responsible for it.
