“There are very few African-American men in this country who haven’t had the experience of being followed when they were shopping in a department store. That includes me. And there are very few African-American men who haven’t had the experience of walking across the street and hearing the locks click on the doors of cars. That happens to me, at least before I was a senator. There are very few African-Americans who haven’t had the experience of getting on an elevator and a woman clutching her purse nervously and holding her breath until she had a chance to get off. That happens often.”
