Hundreds of samples taken from riders in this summer's Tour de France found no signs of doping, officials say. The epic race, which was put on for the hundredth time in 2013, has been at the center of recent doping scandals.
Anti-doping officials say they took 202 blood and urine samples before the race began, and an additional 419 during competition. Nearly 200 of those samples were taken with the goal of creating a "biological passport" for riders, to establish a baseline of their body chemistry.
The Trayvon Martin shooting is at the center of a new video that advocates changing gun policy. The internet video reenacts George Zimmerman's shooting of the unarmed Florida teen, and includes tape from the 9-1-1 calls that night.
