Racing Draws Line at a Chechen Leader's Horse.

Thoroughbred racing has always attracted a mix of royalty and rogues. Blue bloods like the Whitneys and the Vanderbilts have long been owners. So, too, have mischief-makers like the mobster Arnold Rothstein, who won the 1921 Travers at Saratoga with a racehorse named Sporting Blood. It appears, though, at least in New York and in Kentucky, that there are limits to who can race a horse. Officials in those states have taken steps to exclude from racing a horse owned by Ramzan A. Kadyrov, the leader of Chechnya, who has been accused by human rights groups of murder, torture and other abuses over the years. [ABSTRACT FROM AUTHOR]
