Mate, you do the crime, you do the time.
If it was not a crime, let him go home and relax, kick back and enjoy the week.
On the otherhand if he committed a crime - I'm sorry but we are all responsible for our actions and must face the consequences. Too often do we see this PC world excuse someone because we no longer believe people have to stand up and be responsible for their actions.
I hope he gets all the help possible just like any other person would be entitled to. Let us not pretend this was not what it is: an action designed to cause a reaction. Unfortunately that action involved the breach of rights of other innocent civilians.
