Let us hope the jury ignores all that because it's unproven innuendo not directly related to this case. DVC gave us his learned opinion that none of this will be admissible. Therefore the only way the jury will ever learn about any of this is that they've encountered it outside the trial, and if juries consider what they see on television or here on the Internet they'll likely think Zimmerman shot a twelve year old black kid in the back as he was walking home from school.
You DO realize that this same police report was issued when Zimmerman was arrested, taken in, interviewed, and ultimate found to have committed no crime, right? Seems difficult to believe that anything in that report will prove Zimmerman guilty of murder when the report wasn't even enough to bring any charges.
I'm not sure if you're alleging that Zimmerman beat up himself after murdering Martin or that Zimmerman's nose spontaneously exploded, but there is rather a lot of evidence that Martin went after Zimmerman. As to encountering Martin without following him, that seems pretty straightforward: Zimmerman was looking to see where Martin had gone. Martin hadn't gone anywhere except into the shadows because his primary concern was not getting away, but simply being free to talk to his girl without parents or siblings around. At that point either Zimmerman sees and confronts Martin, or Martin sees and confronts Zimmerman, or they happen upon each other; we don't know which, but it appears that legally there isn't any difference anyway.
You seem to think Zimmerman has some obligation to stay safe in his truck, relegating the freedom of the outdoors to the thugs. Let each man or woman huddle alone and just hope the predators prey on someone else. Some feel the same way about Martin, that he had some requirement to run home if he sees someone watching him. Neither is true.
There are some very important lessons here - what your clothing and mannerisms say to others, the consequences of our assumptions based on others' clothing and mannerisms, the value of basic politeness, the added weight of responsibility when going armed - but I'll be damned if a huge part of our nation isn't determined to avoid them at all costs. If one takes either the position that Martin was a thug better off dead or that Zimmerman is a deranged murderer, one is embracing ignorance. I sure hope it's comforting 'cause it's damned ugly to watch.
