I'd like to preface with we all know the early info is often way off...
Hey Dad, WTF? Buying a 14 year old a rifle when strong evidence shows some issues? Not minor stuff, FBI level stuff? My first thought, he is an accessory.
I hope this won't result in laws trying to mandate locking guns up in Gov't approved cabinets. IF Dad aided, a trial makes sense to me. YMMV
