The official police report (which has been posted on FR) provides this.
In addition, medical reports from the Emergency Room where he was taken could also provide support or refutation of Zimmermans version of events.
He didn't go to the ER. The police report specifically says that after he was treated on-site, they didn't see the need to take him there. He instead was taken to the police station.
Thanks. I have not seen the police report. Was it a true copy of the entire police report?
