A man convicted of ambushing and executing an NYPD officer from Long Island and his partner in 1971 is being granted parole.

Anthony Bottom was one of three members of the Black Liberation Army who assassinated NYPD Officer Joseph Piagentini, of Deer Park, and his partner, Waverly Jones — who was Black.

One of the attackers died behind bars, and Herman Bell was let out of prison two years ago.

Diane Piagentini, Joseph’s widow, had hoped this day would never come.

“It's an injustice to my husband, it's an injustice to me, and it's an injustice to my children,” she told News 12 from a playground that bears her late husband’s name. 

The two officers were lured to a housing complex in Harlem with a phony 911 call. When they arrived, they were ambushed from behind with a hail of gunfire.

Officer Piagentini was shot more than 20 times, after reportedly pleading for his life, telling the gunmen about his young children.

Diane Piagentini is blaming Gov. Andrew Cuomo for letting convicted cop killers out of prison, citing executive orders that told the parole board to focus more on a prisoner's rehabilitation instead of the original crime. Gov. Cuomo’s office did not return a call to comment.

Bottom has earned various degrees and established social programs during his time in prison. He is expected to be released next month.

Pat Lynch, the president of the Police Benevolent Association of the City of New York, called state leaders “cowards and lunatics” for allowing Bottom’s release.
