Dr. Drew On Call

HLN’s Dr. Drew told his viewers Tuesday night that he wanted to move the conversation about Trayvon Martin's death forward -- getting into why so many people have such divergent opinions.

"It seems whenever the conversation turns to race, people can become divided," he said.

HLN's Dr. Drew and his guests discuss how the killing of unarmed Florida teen Trayvon Martin has sparked a national conversation about race and justice.

The media and Trayvon Martin's shooting death: Has the reporting been fair or has George Zimmerman already been tried and convicted?

A leading expert in the field of forensic voice identification tells CNN "with reasonable scientific certainty" the person crying for help on a 9-1-1 recording just seconds before Trayvon Martin was shot to death is not George Zimmerman.

The results of that analysis cannot be considered 100-percent accurate, and directly contrasts the Sanford Police report which says that George Zimmerman stated he was the person screaming for help.
