According to published standards, it is inappropriate to draw any conclusion. Insufficient evidence. There shouldn't be ANY expert opinion, beyond that it is not possible to form an opinion from the evidence provided.
That said, this is the family's expert, opining outside of court. Their counsel is in the process of trying the case in public. Crump is just another race-baiter.
Yes, exactly. That is what "inconclusive" means. But I still go back to the fact that there is an eyewitness who both heard and saw Zimmerman yelling for help, and I'm not sure why an "audio forensic expert" would be needed at all. I do understand how the story feeds the sensationalism of the reporting...
I feel great sorrow to Trayvons parents but their anger is misguided. Its not George that took their son; its the Thuggish society Tray fell into. There is where blame lays.
