Convictions for 20 Protesters Who Blocked a Police Doorway A criminal court judge in Manhattan convicted all the defendants in one of the biggest group trials in recent years over a political protest in the city. The trial drew additional attention for counting the civil rights advocate Cornel West among the defendants. They were arrested Oct. 21 while standing in front of a police station door to protest the stopping, questioning and sometimes frisking of hundreds of thousands of people annually. Mr. West said Friday that the court "did justice." He added, "I disagree, but that is what democracy is all about." Convicted of a violation, he and 18 of the others were sentenced to time served, the relatively brief period they were in custody after their arrests. One defendant, a performance artist who got into a vehement exchange with prosecutors on the witness stand, was sentenced to two days of community service. Prosecutors said the protesters had blocked the sidewalk and entrance to the station house, and ignored an order to move, even after a police captain went to them one by one to warn that they would be arrested. The protesters followed police instructions to leave a path on the sidewalk, they and their lawyers said, and no one was kept from entering or leaving the station house, which had two doors. The police orders were confusing and sometimes inaudible, they added. The New York Police Department conducted more than 684,000 of the street stops last year. The police say those stopped were behaving suspiciously - by moving furtively or carrying a pry bar, for instance - but they were not necessarily suspects sought in any particular crime.
