The police killings last week of Alton Sterling and Philando Castile demonstrate quite clearly that even though guns and gun rights proliferate in this country beyond all reasonable boundaries, black men with guns are just as endangered now as they were during slavery. See the following URL for an article in The Atlantic magazine which contains quotes from an interview with Dr. Ronnie Dunn, a friend, colleague, and former student, on the rights of black gun owners.

A Note: Ronnie Dunn and I wrote a book on racial profiling by the police that was published in 2011.
