BS. The 911 tapes are out.
We know, from Zimmerman's own call to 911, that he identified Martin as a black kid in a hoodie. We know that Martin saw him, aced him up , and then ran away, and that Zimmerman pursued him. This makes Zimmerman the clear aggressor. All the talk about how Martin ran up and attacked Zimmerman are out the window. They're wrong. The end.
We know, from reports, that several witnesses, as well as Martin's family, have identified the voice pleading for help as that of Rayvon Martin. And we know that the shouts for help went on for quite some time before Martin was shot.
We know that at least one person has alleged that the local police tampered with testimony.
And, of course, we know that Zimmerman shot Marvin.
We don't know George Zimmerman's version of the events, but we know that his father wrote that George stated that he didn't follow Martin, and we know that this is false, according to the 911 tape.
The police, here, seem to be completely delusional.
