short answer, don't give any dysphoric person a gun.
I watched documentary UK crimes Prime vid last night.
The first one was a woman, --all good in school etc-- who at 14 got together with boyfriend 5 years older and left home. Parents tried to keep them apart cause they didnt like the boy at all.
So girl leaves home with the boyfriend at 14 and the parents dont hear from here again for 10 years, until they see her being booked in for 14 murder spree over time with a huge!!! --short sword--. Totally psychotic individual and on hard drugs etc. She had 6' 2" boy friend who drove her around town to witness her walk over to strange men walking their dogs, and stab only men, many times.
This is out in aytime public areas and the end of her killing spree, when there car was identified. On camera getting booked in station, she is laughing and attempting to make fun of the arresting police officer. So brain all there, but empathy centers shut off, and as stated above, total psychotic killer mentality.
I could not finnish the program. My brain was very tired. No plans to watch any more of that doc. series.
