That's all pretty valid speculative questions. Basically your theory is GZ figured he could jump TM and give him a small beating or maybe just hold him for the police. But when GZ ended up underneath getting his head bashed against the sidewalk, he used his gun. Is that about right? Or do you go further and theorize that GZ inflicted his own injuries (e.g. falling backward)? Basically GZ, the vigilante klutz?
It does not matter how ugly or dumb or black TM;s girlfriend is. It does not matter if TM had a record. It does not matter if TM smoked weed on a regular basis. It only matters what happened that night.
Agreed.
I am saying it is not s drop dead certainty that it happened the way GZ said it did.
