You know what argument never really works? The old “I am not a racist because I put my lips on a black man during CPR in 1993” one. To be fair, I do sorta feel for the guy who arrested Harvard prof Henry Louis Gates a little because it is possible he is a bit dim and a not very good cop and really uptight and controlling and a little nuts, instead of a racist. Or I did feel that way! Until an anonymous Cambridge cop told the Boston Globe: “The fact that the Police Department dropped the charges [against Gates] makes the police officer look like he is wrong.” Oh, wow.
