I think anonymity would be best in this situation- so as to curb retaliation violence. It's the revenge mindset of murder that keeps gangs running so well- You killed my friend, so now I have to kill you, and then your friend will have to kill me, and then my friend will have to kill him, etc, etc, etc...
even if the courts ordered it, it shouldn't be known who actually pulled the trigger, gave the shot, flipped the switch, released the hounds, etc.
