NPR's Margot Adler reports on the 50th anniversary of the Peekskill riots. Controversial black singer Paul Robeson performed a concert in Peekskill, N.Y. in spite of much anti-communist sentiment. At the concert a cordon of union men protected the singer. After the show, a riot broke out as the cars were leaving the outdoor venue with much stone-throwing and racial taunting. Yesterday a service of remembrance and reconciliation was held in Peekskill.
