TM had a destination and was only going there, not creeping around. It was his dad’s or step dad’s place right?
GZ was on the lookout for people up to no good. He saw someone he thought matched that description, and called the cops. They told him to not follow. He did anyways. He had a per-conceived notion about this person’s intentions as evidenced by his statements “these assholes always get away”. He pursued TM.
He had a gun, ready to fire, and knew that he had lethal force at his finger tip. He was supposedly just following the guy so he could help the cops interrogate the guy.
His role as an observer changed to one of a participant the moment he got within physical range of TM. He should have backed off, or maybe even displayed his weapon. Either of those would have prevented a hand to hand situation. GZ got close enough to TM and presented enough of a threat to him, that an altercation occurred. This altercation would NOT have happened had GZ kept his distance.
TM was being actively pursued by an individual who was not law enforcement, did not identify themselves as such, and was stalking him for a period of time. Who’s to say TM wasn’t defending himself? I doubt he would have charged a pistol wielding “neighborhood watch” psycho packing heat.
GZ, by his own admission, put himself into that situation. He was free to leave it to the cops at any time, and chose not to. He was the one that was armed, and he got close enough to the person he was trailing in order for there to be an altercation. In this altercation, he shot his prey in the chest, in the heart no less.
He brought a lethal weapon with him when he confronted someone he had no business confronting at all. If TM did the confronting, he was protecting himself against some random guy in the street, not an identifiable member of law enforcement.
GZ should not have been pursuing TM at all, and had he produced his weapon prior to them being in proximity, the situation would have ended differently.
GZ’s story is “I was trying to prevent crime, so I followed this guy with a gun on me, and we got too close. He was beating me up, so I killed him.” WTF?
GZ brought a gun to what wasn’t even going to be a fight. He made it one by either antagonizing, or proximity or both. He killed a kid, and it was justified because he was scared after he went at a kid with a gun.
