The coroner who conducted Kelly Thomas’ autopsy said the homeless man died from lack of oxygen caused by chest compression during his struggle with police.
Thomas became brain dead "due to mechanical chest compression with blunt cranial injuries sustained during physical altercation with a law enforcement officer," Singhania said. “The chest got compressed, that caused [Thomas] not to breathe.”

That doesn’t answer my question. Wasn’t he lying to the cops when he said he couldn’t breathe? He was talking loudly and nearly nonstop.
