For two-time NBA champion Isiah Thomas, who is a native son of Chicago -- a city plagued by violence and gun crime -- part of the solution is sport. "In a simplistic form, play gives you the ability to get to know someone," says Thomas. After retiring, he helped form the Toronto Raptors in Canada -- the only current NBA side located outside the US. He was speaking to CNN on the eve of the NBA game between the Indiana Pacers and the Denver Nuggets that takes place at London's O2 Arena Thursday. This is the seventh time a regular season NBA game has been played at the O2.
