BENGHAZI, Libya — The killing was not a shock here, in the city where Libyans started their quest to shake off dictatorship and now struggle, nearly two years later, to douse the simmering violence that is a legacy of the revolt.
One evening last week, a car screeched down a residential street. Three men stepped out and with startling ease gunned down Faraj Mohammed el-Drissi, the man whose job it was to ensure this city's security.
Mr. Drissi, who had been on the job since October, was among roughly three dozen public servants killed over the last year and a half, including army officers, security agents, officials from the deposed government and the United States ambassador, J. Christopher Stevens. In all the cases, no one has been convicted, and in many, no one has even been questioned. That is unlikely to change anytime soon.
