Anger as post-mortem tests following Stephon Clark shooting dispute police account

Post-mortem tests which show an unarmed black man was shot in the back by two police officers in Sacramento, California - contrary to an official statement - have sparked widespread anger and calls for criminal charges.

A day after the fatal shooting of Stephon Clark on March 18th, Sacramento police said in a press release that the officers who shot him "saw the suspect facing them, advance forward with his arms extended, and holding an object in his hands".
