The Self-Refuting Expert Witness The Orlando Sentinel Is Touting

Back on the Trayvon Martin killing audio expert Tom Owen is getting good press with his claim (broken by the Orlando Sentinel) that it is not George Zimmerman heard screaming for help on a 911 call.  Here are CBS, CNN, MSNBC, Mediaite and the Boston Herald.
I squawked that other experts would question that conclusion - a good forensic audio match requires examples of speech similar to the sounds being compared.  So using George Zimmerman's spoken voice on his 911 call and comparing that to the screams heard in the background of a second 911 call would be a no-no.
Interestingly, in describing his techniques at his website, we see that Tom Owen agrees (my emphasis):

It seems to me that whomever is proved to be screaming on the tape has an upper hand in winning their case. It seems strange to me that both the friends of Zimmerman claim that it is he who was screaming and the mother of Martin claims that it was her baby who was screaming. If it was Martin, Zimmerman is in big trouble. They better get this right!
