In this Sunday, July 29, 2012 photo, South Africa's Cameron van der Burgh, bottom, and Italy's Fabio Scozzoli compete in the men's 100-meter breaststroke swimming final at the Aquatics Centre in the Olympic Park during the 2012 Summer Olympics in London. As controversy swirls over alleged illegal dolphin kicks by van der Burgh in his 100-meter breaststroke victory last week, swimming officials are debating introducing underwater video use for judging. Van der Burgh has acknowledged that he took an additional underwater kick at the start of his world-record swim, justifying it by explaining that most competitors do it. (AP Photo/David J. Phillip)
