That's your opinion.
The law only requires Zimmerman to believe he was in danger of serious bodily injury or death.
Having been one, and somewhat of an expert (albeit some years back) I can tell you Paramedics have absolutely no power to force an injured person to seek medical care if that persons refuses medical treatment.
I don't find it odd at all and, inserting the words "by the time he pulled the trigger" exceed the scope of the law again. All Zimmerman has to claim, and I don't know what he's specifically said about the incident, is that he believed he would be killed or seriously injured if he didn't use deadly force. He doesn't have to claim he had already been seriously injured (or killed).
All a jury has to believe is that it was reasonable to believe that.
The injuries are consistent with the account attributed to Zimmerman, and the evidence known to the public.
Heard it somewhere.
Well, since the altercation appears to be what ended the phone call to his girlfriend, I'd say you're right, he didn't have time to run from point 3 to point 5 before being shot.
But, the call with his girlfriend didn't end when Zimmerman was on the phone with police as he sat stationary at point #3 and exclaimed Martin was running and I doubt it ended before Zimmerman got off the phone with police 1 minute and 59 seconds later. Plenty of time for Martin to run a damn long way.
How'd he end up at point #5 at the end of his conversation with his girlfriend?
