Though only 18 years old, two of them were hanged. The chief instigator ("Flossie Forsyth")was said to have screamed during prison exercise- "I don't want to die"- he ran and struggled. He cried all night before his execution. Death by youth was somewhat rare then- I wonder why?.
Now death by youths is not uncommon in that country- or other countries. I would use an old statement by an English magistrate.
"Men are not hanged for stealing horses. They are hanged to prevent horses being stolen". Bring back the noose.
