How would you react if you saw a woman being stabbed right in front of your eyes by a man?

I've never tried starting a petition but I am compelled to for the 26 year old driver who saw this happening and tried to do something about it by driving his car into this horrific act to stop it.

He is a hero. He is our #maidavaleherodriver

He does not deserve a prison sentence. He acted to stop this horror.  He must be in complete shock by seeing this stabbing and is not a murderer...it should be diminished responsibility. He tried to protect the woman.

The stabber is the murderer as he had an intent to kill but the driver just wanted to stop it.
