A deathscort plying his trade outside of a Planned Parenthood in Ann Arbor, MI, repeatedly committed assault and battery against a sidewalk counselor while the latter was engaged in a conversation according to this report by Jill Stanek. This attack was witnessed and charges were filed. Thus Bernie Klein is to be arraigned in district court on January 20, 2012.
Go further down Stanek's piece and you'll see Mr Klein has quite a chequered past. On the news clip his name is mentioned in conjunction with the "Final Exit Network", an assisted-suicide (i.e. murder) network. Given his fascination with murder, Klein's 21 years of deathscorting makes sense.
