Attached below are a couple of links to videos from a group called the Center for Urban Renewal and Education or CURE. They have a couple of videos related to gun control and its roots in the persecution of African Americans. One of the videos is pretty in your face, but also probably an accurate depiction of that history. The second is a series of short statements by African American leaders on the subject.
