Twenty “offensive” Facebook posts about the West Indian Day Parade have been matched up with names of police officers, Police Commissioner Ray Kelly said today.

The officers now face Internal Affairs Bureau questioning over comments that participants in the annual Labor Day weekend parade are “savages” and “animals.”

“It is disturbing when anyone denigrates a community with hateful speech. It is unacceptable when police officers do it,” Kelly said.

Though the officers may claim their comments are covered by the First Amendment, Kelly said the Police Department “reserves the right to discipline behavior it determines to be unbecoming of a police officer or detrimental to the service, especially when it is disrespectful of communities that officers have taken an oath to protect.”

Internal Affairs detectives have begun questioning the officers and will subpoena computer records “where necessary,” Kelly said.

The annual parade along Eastern Parkway in Brooklyn is the city’s biggest, drawing more than 1 million spectators a year.
