Having done some reading up on this case (on this source
https://en.wikipedia.org/wiki/Shooting_of_Trayvon_Martin ; not normally always to be fbe fully trusted, but I think in this case the text can be considered accurate), I come to the following conclusions
1) Martin was unarmed, while Zimmerman was
2) Zimmerman carried a gun legally
3) Zimmerman found Martin’s behavior prior to the incident ‘suspicious’. This seems to have been justified.
4) Zimmerman did not go after Martin (as he was told to do after calling the police with his suspicions)
5) There are no eye-witness reports (known) of that fatal incident, other than the one survivor: Zimmerman.
6) Zimmerman’s various testimonies show no inconsistencies. Also his spoken report on what happened has been checked through a ‘voice stress’ test (some sort of lie detecting check); no indication of lies or attempt to change came forward (i.e. he wasn’t lying).
7) Autopsy on Martin showed no trace of physical violence prior to the shooting.

Zimmermann showed multiple wounds inflicted through physical violence experienced right before the shooting.
9) In the recording of the 911 call (made by Zimmerman) multiple calls for help can be heard; it has been established beyond doubt these calls came (all) from Zimmerman.
10) Autopsy on Martin showed traces of drug use, although is such low levels that he probably wasn’t under influence at the time of the incident.
11) There is no evidence of racist tendencies on Zimmerman’s side (rather the opposite). There is evidence of racist tendencies on Martin’s side.
12) Media coverage was very much tilted to Martin’s side and against Zimmerman, to the point of deliberately and deceptive coverage and even editing the 911 call by CNN and NBC.
13) Even President Obama made statements that supported the ‘racist victim’ when the trial was underway.
Insofar as I feel save to draw conclusions:
1) Was Martin the victim of (2nd degree) murder? No.
2) Was Martin the victim of racist induced violence? No.
3) Was Zimmerman the victim of (unprovoked) violence by Martin? I lean to yes.
4) Was Martin shot in an act of self-defense by Zimmerman? I lean to yes.
I have seen no evidence on which Zimmerman could (or should) be convicted, with the possible exception of involuntary manslaughter (which doesn’t mean there could not surface any; I base myself here in what I know of the case so far, which is that I see no evidence for conviction)
What does this whole tragedy give as signal? That in the US any violence case between ‘different races’ will be the hijacked by ‘supporters’ of both sides, be the victim of twisted and untrustworthy media, hype and sometimes understandable but nevertheless unjustified emotions on both sides. Oh, and that widespread gun ownership isn’t a good idea.
All best,
