It's a mess now. There's a whole lot of WTF in the events and how it was handled.
It appears that Zimmerman instigated the entire thing by following Treyon, and there hasn't been a good explanation as to why he got out of his vehicle. He said he didn't know the address, yet he was in his complex -- BS meter goes up there.
Zimmerman has a past with two assaults and batteries in it, with the Felony Battery on a Police Officer dropped down to a misdemeanor. The other was a charge of Domestic Violence.
Treyon's background is now coming to light, and he was certainly no Saint. I think he and Zimmerman got into a verbal confrontation, and then he suckerpunched Zimmerman, continuing on to beat the snot out of him. Zimmerman then shot him.
The racist angle is valid. There's been racism up there for a long time, and the history of Zimmerman's 911 calls was showing he was suspect of Black folks. However, in the end, I think the problem lies with the police department.
The whole bandwagon of people Tweeting, posting pictures of themselves wearing hoodies, Black Panthers putting out a bounty on Zimmerman -- that's crossing the line. It won't matter if the facts show that Zimmerman did shoot in self defense, as the goal of turning it into a racially motivated act.
And then, with all of the media coverage of this, playing the race card, none of the news outlets cover something serious when it's black hurting white, in a blatant racist attack:

For what it's worth, I 'blame' Zimmerman, though I don't think it was an intentional homicide.
