After positive drug tests for two of the world's top athletes, Asafa Powell and Tyson Gay, we speak with Andre Lowe, the Jamaica Gleaner reporter who broke the story about Asafa Powell's test, and to AP's Patrick Graham, who'd spoken with Tyson Gay after his test became public.

We get more reaction to the acquittal of George Zimmerman over the killing of unarmed Florida teenager Trayvon Martin. We speak with a friend of the Martin family, Linda Dayson as well as John Phillips, attorney for the family of Jordan Davis, an unarmed black teenager who was shot dead in Florida nine months after Trayvon Martin plus Emily Bazelon, a senior editor at Slate magazine.

We also get Australian reaction to the first Ashes test result with Drew Morphett, a cricket commentator with ABC in Melbourne.
