Eggzactly.. why on earth would anyone think screaming for someone to come help you win a fight is gonna get the guy winning the fight to stop attacking you.
More particularly why would a hispanic guy ask a white guy to help him restrain a black guy? Wouldn't the black guy get even more angry at the hispanic guy for asking the white guy to help him? duh?
It's almost as if GZ does not want the guy to stop. Or more particularly that he's really just trying to stop TM from "getting away."
You're making the argument for me there. "Stop attacking you" is continued aggression. Which would be precisely why a person would have a reasonable fear of death or great bodily injury.
I understand your point. How can I explain...
When two guys meet in the middle of a yard that have been doing the dance (following each other and making obscene gestures)... it is not unusual for a verbal and / or physical interaction to occur. It happens.
Typically most of those interactions do not escalate. However, when issues of race are involved, and when prior acts are fresh in the minds of the two parties, they will sometimes do things they would not otherwise do. TM was freshly suspended (fact) and looking for someone to take it out on.. (my guess) GZ was freshly disappointed by "them getting away" (fact).
Thus it's not imagination to say one or both of them caused, in part, the incident to occur. GZ through negligence and stupidity, TM through youthful bravado and anger.
Given that they are in a fight..
there are unwritten rules in any given fight that civilized men are expected to adhere to. For example, you don't stab or shoot someone cause you lost the fight.
Stupid rule? Suicidal rule? Maybe... What we have is a society that simultaneously pushes for ZERO tolerance, but somehow 100% tolerance is expected in cases of self defense.
IMO there needs to be some sort of civil code where escalating a fight from fist to weapons is seen as an escalation. You appear to argue the busted nose and scratches and accusation of strangulation are evidence that he had to kill him.. but the nose was minor, the scratches, minor and the strangulation has no proof.
