FILE -Detectives take Bernard Goetz to his arraignment Thursday, March 23, 1985 in New York. Goetz was charged in the subway shootings of four youths, who allegedly accosted him and asked for money. The shooting this week of 10 people by a man who deployed smoke grenades and fired at least 33 shots in a commuter-packed Brooklyn subway car was hardly the first time New Yorkers have grappled with an act of violence.
