Leave the perp walks for the convicted. Sometimes even convictions are wrong.
I agree. Objecting to "perp walks" for those the state has only accused of crimes (unlike naming the alleged victim in cases involving allegations of sex crimes, their agricultural policy, and much of their foreign policy) is something the French get right: it does contradict the presumption of innocence by creating pre-trial publicity in which the accused in portrayed as the perpetrator of a crime.
