Dr. Michael Baden during a news conference Monday said police and prosecutors will make a decision whether to charge anyone in the Aug. 9 killing of an unarmed black teen in Ferguson, Mo.
A woman asked Baden, who performed an autopsy on Sunday, about Michael Brown's injuries.
"I'm assuming he could have survived. Am I correct?" she asks.
"He could have survived. All of these gunshot wounds were survivable except for the one in the top of the head, that went through the brain," Baden replies.
"That seems sad," she responds. "All of us here know what happened to Michael. Why hasn't Officer Wilson been arrested?"
Baden replies, suggesting politics some times trumps science.
"Who gets arrested is a political, district attorney decision and not a forensic science decision, for good or for bad," he said.
Baden, a renowned pathologist who has worked with the New York state prison system as chief coroner for more than three decades, is often called in as a expert in high-profile cases.
Baden's determination that Sandusky County jail inmate Craig Burdine was the victim of a homicide at the jail in August 2007 was over-ruled in July by a grand jury hearing information from Ohio Attorney General Mike DeWine's nearly year-long investigation launched six years after Burdine died. The grand jury did not return any criminal indictments.
Burdine's family contends DeWine whitewashed evidence and helped cover up what happened to Craig Burdine at the jail.
