You claim to want PROOF, and now You are misquoting Abe Zapruder right after You misquoted Bill Newman. Zapruder did Not say he heard shots fired from "RIGHT Behind Him". Zapruder did WC Testify to DPD motorcycle cops being Right behind him, but he did Not claim the shots fired were "RIGHT Behind Him".
Go in circles all you want. He said he was in direct line of fire to paraphrase him in his TV interview and his Warren Commission testimony he stated:
Mr. LIEBELER - Did you have any impression as to the direction from which these shots came?
Mr. ZAPRUDER - No, I also thought it came from back of me. Of course, you can't tell when something is in line it could come from anywhere, but being I was here and he was hit on this line and he was hit right in the head--I saw it right around here, so it looked like it came from here and it could come from there.

Fact is fact, get used to it.
