That has been tried when he was being released from the childrens system after his assault (?) conviction.
He went to court to prove wanting to kill his mother in that way did not make him insane.
There is a whole court judgement document which was circulated at the time of his arrest.
Its grim reading as his father was a violent abusive man and he was taken into care himself due to his attacking his mother.
The judge agreed that he was sane and referred the plans to murder his mother to the police which resulted in the current conviction.
But this is a great chance for all the Irish "TWAW and what a poor dear child she is" TRA to offer a bedroom or a sofa for the cause 😬
And this time Tusla can fuck right off with trying to supress his history and VAWaG
