The facts are, GZ profiled then followed an unarmed young man, when he had no authority to do so. He exited his car, and STARTED to antagonize this same young man, still without the authority to do so and against the protest of the 911 operator he was speaking with....
What happened next is (to you) up for speculation. Who threw the first punch? Who was on top of who... All things that no one was there to witness, and no cameras were there to record. So, what evidence of this do we have....nothing more than GZ's testimony. Because the only other witness to the situation was shot dead.
So here we are, with only one side of a story to hear. Which is that a young boy, half the size of GZ somehow wrestled the man to the ground, and started to assault him. Allegedly breaking his nose and causing abrasions to the back of his head.
So GZ is placed in police custody and taken to the police station, where a video shows no evidence of injury, but pictures taken later show a bloody head and nose. Why the inconsistency in the visibility of injuries...? Apparently there's an infinite number of reasons that could be used explain that inconsistency, so to you, the idea of foul play is just impossible. You believe all official reports, I guess...because they're "official"...
While I don't believe the "official" reports because of the inconsistencies in the testimonies, evidence and a few other things....WITH the addition of my belief in systematic racism.
Which, IS a product of my awareness of past cases of judicial misconduct in favor of racial discrimination, prejudice, and oppression. That is my stance on this issue. The FBI and other authoritative agencies CAN lie, because they HAVE lied before. Did they lie here, maybe so, maybe not. I believe they did, you choose to believe they didn't, which doesn't surprise me. There is no further explanation needed here....
