So let me get this straight, GZ's defense is "I followed around TM in the dark, he attacked me defending himself, giving me some cuts and might have broke my nose. TM didn't have the right to defend himself with his fists because someone was following him around in the dark and he felt threatened, so I used my right to blast him because I thought he was going to get my gun that I was carrying around while following him in the dark."
I don't care if everything GZ is saying in his defense is true, there should at least be some law that puts him away for double-digit years for wrongful death for following around someone in the dark while carrying a gun. A reasonable person would think "Hey I'm following around someone in the dark while carrying a gun, there is a good chance that this could lead to an altercation where the gun is discharged with a risk of death." If Florida doesn't have a lesser wrongful death, 10-15 years minimum in prison law that's applicable to this situation and available to the prosecution to present as a lesser charge option, that's mumped up.
