Hi clo,
You're going in circles.
CA was found not guilty because the burden of proof is on the prosecution.
Z is also protected by the burden of proof.
You find it hard to believe he talked after being shot but the PROSECUTION's expert witness said he would not have died for at least a minute.
Eyewitness testimony confirms M was on top beating the crap out of Z. The state of his head confirms it. Broken nose. Welts etc.
I get the program. Ignore the inconvenient truths. Repeat the prosecution theories. Make up stuff. Put some guy in prison for defending himself. Who cares. It ain't you serving time for nothing.
