AThank you for this. IF this goes further, it would be the most compelling defense for Z. But let me ask you something.
Do we know anything about Z? I mean we the judge has surpressed the prior conduct of M which paints him clearly as a racist thug, but how about Z? Was he a rational person? Was he quick on the trigger before? Any prior felonies? How many times did he call 911?
You need to get up to speed on the case. Excellent end-of-day wrap-ups with a lot of video are here http://www.legalinsurrection.com
