Here's a thoughtful and thorough review of The Silence Of Our Friends up at Scapegoats And Panaceas.
"There are few indications that well-intentioned white southerners or noble white activists, while present in the historical record and active during the movement, are actually representative of the Black Freedom Struggle. Yet Long’s account succeeds admirably in fleshing out the intimate and thorny exigencies of interracial friendship during difficult times. He and his co-authors succeed by not white-washing complexity."
