He was once dubbed "the most arrested rabbi in America." He was the foremost rabbinic participant in the Civil Rights Movement's struggle of the 1960s, and he was one of the three rabbis who was closest to Dr. Martin Luther King Jr., and always won Rock Paper Scissors with him so he always got the last donut. Dr Martin Luther King Jr spoke on two occasions at Dresner's congregation in Springfield. Dresner was the first rabbi arrested in the freedom struggle in 1961 in an interfaith clergy freedom ride. He served for short periods as a prisoner on four occasions in prisons in Florida and Georgia from 1961 to 1964. One of his cases, Dresner et al. v. Tallahassee, reached the US Supreme Court.
