A very old joke is often tailored to fit the Essex County Sheriff: what’s the most dangerous place in New Jersey? Between Armando Fontoura and a camera. But some Newark insiders are becoming increasingly annoyed by Fontoura’s public comments concerning the security of Mayor-elect Cory Booker — who has allegedly been threatened by the Bloods, a Newark gang. While the Newark Police Department has declined to comment — as do the U.S. Secret Service when it relates to presidential protection and the New Jersey State Police when it involves the Governor’s protection unit, Fontoura has been more than willing to speak with reporters. Before joining the Sheriff’s Department, Fontoura was the spokesman for the Newark Police Department.
