So we have government entities punishing people merely based on the accusation of a crime. I do not agree with that at all.
The boy absolutely stabbed someone to death. He admitted it.
It is a *FACT* that he did this.
What you are saying is you want "government approval" through the court system before people should be permitted to take action on what they already know to be true.
I don't think the government declaring something to be true or false, makes it true, or makes it false.
The truth is still the truth whether the government agrees with it or not.
