Attorneys representing the four police officers who remain before the jury in the Abner Louima torture trial were for the most part relieved yesterday when Officer Justin Volpe admitted to one of the most heinous acts of police brutality in New York history.

The lawyers have sought to put as much distance as possible between Mr. Volpe and their clients throughout the trial, in which Mr. Louima, backed by several witnesses, accused Mr. Volpe of sodomizing him with a stick in a police station bathroom in 1997.
