Zimmerman case evolves

The evidence was released in the Martin/Zimmerman case today, including the autopsy results. There have been a few interesting developments in the past few days:

1 Martin was using drugs. THC, specifically. THC both impairs judgment and makes the user paranoid.

2 Martin's only injuries were the gunshot wound, and bruising on his knuckles, and the gunshot was delivered from a distance of less than 18 inches. This shoots holes in the theory that Zimmerman was the aggressor. If he was going to be the aggressor, Martin would have other injuries, or no injuries (other than being shot).

3 Zimmerman had a broken nose, lacerations, bruises, a split lip, and was complaining of a back injury.

So far, not one piece of evidence has been released that contradicts Zimmerman's version of events. While it is possible that Zimmerman was in the wrong here, we don't convict people on possibilities. We need proof beyond a reasonable doubt. As long as Zimmerman's version of events stands up to scrutiny, it remains a possibility. As long as it remains a possibility, that possibility makes self defense that reasonable doubt. As long as that doubt exists, Zimmerman cannot be guilty.

Edited to add: The  levels of THC (1.5 ng/mL) in the blood were low enough to show that Martin had not smoked marijuana within the last hour or so, and so low as to mean that he was probably not impaired at the time of the shooting. Levels in this range have been shown in studies to be present for up to 48 hours, so all the test shows is that Martin had been smoking marijuana within the last 48 hours.
