So we're going with the "it wasn't even TM that was punching Z angle"? So, despite eyewitnesses that never lost direct observation of Z after the gunshot, he MAGICALLY beat his own face and lacerated the back of his head and no one saw it?
No. The story is, "suffocating, arm slamming, continuous smashing head" and therefore, "in fear for life."
So, if there is a bloody nose there should be Zim blood on Trevon's hands, clothes, sleeves, etc. There is not.
And the rain is the same. Even though Trevon has almost no injury, there is Trevon blood around.
Same rain. So, there would have to be blood of Zim on Trevon somewhere. They can find his blood.
But, the guy with "not really" broken nose.... there is none of that blood on Zims merciless killer Zim NEEDs to dispatch. But that too is a lie, in another evidence trail of aiming and centering his weapon on the heart.
Nose smashed after. Concrete squirmed ONTO to bonk his own head. Worked out a license to kill scenario with his friends, I think.
