What, exactly, did happen? Was it murder? Was it an accident? Was it justifiable homicide? Was poor training involved? Facts are immutable things! I wasn’t there! So, at the moment, I’m not in possession of the facts!
The only facts we will get on this will be the CCTV footage and the eyewitness accounts from bystanders and cops. After that, we have to make our own best judgment. If you want immutable facts, you will never get them, therefore you can never make a decision, so why comment at all?
