This is how I feel. My deepest hope is that Z is found innocent.
I can tell you this: if T was white, and had the background and lifestyle we're reading about, this would have been open and close, with Z free and living his life right now. But because T was black, and because it's 2013 and we have a half-black president, this has now become a case of racism and retribution against a "white perpetrator" (Z).
Given what is happening with our culture and in Washington DC right now with all of the scandals, cover-ups, lying, and double-talk, and seeing how Americans really don't seem to mind what this administration is doing/has done, this case will not go well for Z (as an extension of the culture shift and as retribution for past cultural sins).
Doubtful.... and on the flip side of that argument, those that will use race to focus on this tragedy would say, that had T had been white, Z would have never followed him.
