A police officer says he pulled over Kirk Johnson's car five years ago because of a suspected violation of Nova Scotia's Motor Vehicle Act -- not because the boxer is black. Halifax police Const. Michael Sanford told a Nova Scotia Human Rights Commission hearing yesterday that he noticed Johnson's car because it had tinted windows he believed could have been in violation of the act. Sanford also told the inquiry that he didn't know who Johnson was when he pulled him over along with his cousin, Earl Fraser, in April 1998. Johnson claims he was pulled over because the pair are black. Halifax deputy police Chief Chris McNeil has denied that the incident was motivated by discrimination.
