And some children are mature enough to drink, vote, drive, get married, serve on juries, serve in the military, etc.. Do you favor a repeal of those restrictions on minors as well?
Yes if a jury of 12 agree and a judge agrees and an appelate judge agrees and the governor and POTUS agree and the child/parent are willing to pay for the proceedings, then the restrictions should be lifted in special cases. For me a psychiatrist and an independent evaluator and the school principle allowed me to skip a grade. Actually, I was cleared to skip 2 grades, but my parents thought 1 would be enough.
There are plenty of safe guards in place to make sure on the truly deserving teen killers are put to death.
