I've read conflicting reports about him refusing medical treatment, at least in regards to going to the hospital immediately after the incident. I only recall him refusing to go see an ENT. Did he have medical insurance? I can imagine that could have played a part in his decision whether or not to further investigate his potential injuries.
We have emergency rooms where people with serious injuries can get treated regardless of their insurance status. Despite allegedly suffering a serious assault, Zimmerman managed to come out of it with only minor injuries.
I'm not going to argue he had a concussion, but I will provide the below link and quote to show that he did describe something similar.
.nervous-system-diseases.com/concussion.html (add www to the beginning of this, I can't yet share links)
There is a spectrum of symptoms associated with a concussion. Not just one. They include dizziness, loss of consciousness, headache, slurred speech, and nausea.
According the the medical records, Zimmerman did not experience dizziness, loss of consciousness, headache*, slurred speech, or nausea**.
* This one I find particularly shocking. They guy said he had his head repeatedly slammed onto concrete. And the next day, not even a headache.
** Denial of nausea is listed under gastrointestinal symptoms, but earlier in the report Zimmerman claimed to experience "occasional nausea when thinking about the violence last night".
He didn't say the "fight" happened at the T, he said that's where the first punch was thrown.
Zimmerman claimed he immediately went down after Martin punched him , where he remained helplessly pinned. It wasn't until he saw the geographic impossibility of his story that he started adding embellishments about stumbling around.
You tell me which version you believe, because they directly contradict one another.
Maybe because the State's star witness will also be "a proven liar" at that point?
I have yet to see the State refer to Witness 8 as their "star witness".
All I know is that it has been the defense who has repeatedly attempted to stall the proceedings, and in the very same hearing in which the State's supposed "star witness" was apparently hamstrung, it was the defense who passed up on a chance top exonerate their client.
What did GZ lie about in relation to the events that took place on 02/26/12? I don't know of a single, proven lie.
In his police interview, he claimed to not have been following Martin, despite the fact that he admitted just that during the NEN call.
He was untruthful about where the altercation took place in his original statement. Whether you want to recognize that as a lie is up to you.
But considering that that lie was in service of his claim to not have been following Martin,
and that he demonstrably lied to Serino about a previous criminal entanglement,
and that he conspired with his wife in an attempt to defraud the court during the bond hearing, I'm not sure how much slack it is reasonable to cut him.
