It also doesn't support Zimmerman's story at all.
Add the testimony of the head homicide Detective and Zimmerman's prior record and it doesn't look promising.
It actually mildly does. when you look at some freeze frames of the video, it appears that there is a gash on his head, which one cop later looks at. In any event, the video is so low quality that it is worth virtually nothing. As for the detective, big deal. Investigators often differ on cases. Others support not charging Zimmerman. Ultimately, it's up to the DA, not a homicide cop. Zimmerman's record includes an assault some years back, not a murder or gun crime or hate crime. I'm sure it will be introduced should there be a trial, but then so will Martin's past, which includes by his own words his own assault on a bus driver. I'm thinking a judge won't allow that, but the jurors will hear it before being told to disregard it if Zimmerman's lawyer is worth anything. Also, his school suspensions will come into play, one of them for weed, and one supposedly for possessing a "burglary kit with some loot".
And Zimmerman's lawyers will certainly ask why exactly his body lay in the morgue for three days without his family apparently exhibiting the slightest concern for him, not even enough to file a missing persons report, or check the morgue, or look into that shooting in his father's fiance's neighborhood. It may or may not have any bearing on the case, but a good lawyer could come up with a theory at least as compelling as anything Martin's supporters have been waving around with little or no evidence that have been taken as fact by the media and a fair bit of the public.
One thing I'm a bit unclear on, (actually, it's everything, since nothing is truly certain in this thing, at least to us), is what happened with Zimmerman's arrest. If it resulted in a felony conviction, it should have prohibited him from owning and certainly carrying a firearm. So what was the deal?
