Woburn Police officer John Maguire was killed in the line of duty during a store holdup on Dec. 26.
After his death, the actions of the Massachusetts Parole Board came under fire by critics who felt career criminal Dominic Cinelli, who police said shot Maguire, should never have been released from prison.
