Here is my thing.
They are free to forgive all they like.
Just don't say you forgive on record. How many times have black children been killed without the killer getting a justful sentance because everyone forgave on record.
Do this from now on. Go home, pray and forgive, but in court, just say you have nothing to say on record. There, problem solved and you have not helped the killer's chance of getting out scott free.
Simple? Sure. Will everyone do it? No. But we need a code where everyone does do it.
