There wasn't enough evidence to be 100% sure that it was 2nd degree murder or manslaughter, simple as that. I think manslaughter might have been the right call.
There's a bunch of people on my facebook feed who are acting completely ridiculous and obviously didn't even follow this trial closely. They think Zimmerman is a serial killer or something.
