You make good points, but Zimmerman is obviously not “white.” Look at his mom and his uncle. They’re obviously HIspanic, I would think largely of South American Indian ancestry. It’s true that they seems to be a very nice family that wanted nothing more than to assimilate into the larger American culture, but that doesn’t make them “white” to anybody but a Democrat!
The all female jury may be a factor. The difference will be if they identify with the mother of a dead son, or with Zimmerman and the fear of a feral young thug.
The good news is that none of them are black. It saddens me to have to observe that black jurors are in most cases unable to look beyond race to find a black defendant guilty or a non-black defendant not guilty.
