 They were met at the post office by a line of Marion police officers, county sheriff's deputies, and Alabama state troopers.During the standoff, streetlights were abruptly turned off (some sources say they were shot out by the police), and the police began to beat the protesters.Among those beaten were two United Press International photographers, whose cameras were smashed, and NBC News correspondent Richard Valeriani, who was beaten so badly that he was hospitalized.
