Kiki Petrosino is afraid when she gets behind the wheel -- afraid that she will be killed by police in a routine traffic stop. In "Letter beginning, 'If My Body is a Text'", she tries to express this fear of being misunderstood by white authorities. This week, we speak with Petrosino about her work, and continue our series on remarkable, untold stories from black history -- this time, in the world of sports.

Plus, we talk to a scholar who is mapping the history of the KKK -- despite descendants' efforts to erase records -- and trace the origin of revolutionary thinking.
