Evidence

However, as with many other prosperous black people, Robert Harlan’s mixed-race family was constantly at risk of being attacked by local gangs of white vigilantes who targeted black businessmen and white abolitionists. 
 Brimming with self-confidence, he believed he could make a success of it, but he could not “risk a long journey without proof of his freedom.” Despite his special privileges, he had lived his thirty-two years to date as an enslaved man. — Dorothy A. Brown, Getting to Reparations, 397
