The large public outcry put me immediately in Zimmermans corner (If a large percentage of the population believes something to be true, it probably isn't).

Then I got the facts, and I felt more Zimmerman was in the right.

I think the biggest indication so is how the arguments are being made. Those that support Zimmerman (or atleast not Trayvon) present facts and long allegories. Those that support Trayvon say everyone who doesn't is racist. Whether Trayvon was in his right to beat someone up or not, making such a point-blank statement defeats the credibility of the arguer.

However the prosecution must believe Trayvon was in the right. If they don't and they do character assassination to get a conviction they don't believe in, that's actually illegal (see Duke 2006 Lacrosse Scandal). So perhaps there is some evidence that hasn't been presented that proves Zimmerman was wrong.
