That's irrelevant.
Not raising your hands does not give a police officer or anyone else the justification to kill.
If deadly force is used there must be a valid reason. In this case either the police officer or other persons lives must be in grave danger otherwise deadly force was not justified. With the facts presented it's very clear no one's life was in grave danger from the suspect as he was unarmed and not an immediate threat. This is minimum, manslaughter.
You wouldn't be a member of FR's rather large "All Cops Are Cold Blooded Murderers" brigade,would you?
