But its not revelvent. I can follow you anywhere I want as close as I want as long as I have a legal right to be there. It gives you no excuse to attack me. When you start the physical confrontation you crossed the line.
It's not relevant if GZ told the truth, the whole truth, and nothing but the truth. Otherwise, it's very relevant. It's only from GZ's statement that we have the image of TM attacking him from the the rear/side. Other scenarios are compatible with the physical evidence, and in my experience the truth usually lies somewhere in the middle.
