it appears to be true:
BOSTON – A Boston police officer has been suspended for using a racial slur to describe black Harvard professor Henry Louis Gates Jr.
After learning of the slur, Commissioner Edward Davis put 36-year-old Justin Barrett on administrative leave pending a termination hearing.
A person with knowledge of the case, speaking on condition of anonymity because the person is not authorized to speak publicly about it, said Barrett, a member of the National Guard, used the racial slur in messages to guardsmen
and to The Boston Globe.
