Three men who were convicted of second-degree murder overturned a table in Brooklyn state Supreme Court and attacked court officers with razor blades and homemade knives, injuring 11 officers, authorities said. None of the officers were seriously hurt, Harold Wolfe a spokesman for the state Office of Court Administration, said. Assault charges were filed against Robert Brodie, 28, his brother, Arthur Brodie, 22, and Michael Sennon, 22, after the melee. A fourth defendant in the murder case, Shannon Kelly, 23, was not involved, authorities said. The four had been searched twice before the incident, but the weapons were not found, Wolfe said.
