The widow of an NYPD officer who was fatally shot in 1971 wrote in a New York Post opinion piece that the release of her late husband's killer "is a betrayal to police officers who are putting their lives on the line now."

Herman Bell was granted parole after serving nearly 45 years behind bars for the murders of two officers, including Joseph Piagentini.

"(Bell) robbed us of our life," Diane Piagentini said on "Fox and Friends."

Bell convinced a panel appointed by Gov. Andrew Cuomo that he was remorseful and reformed, according to the New York Post.

"The worst thing about it is that it is setting a precedent — New York City police officers and officers all over this country are walking around with a bull’s-eye on their backs," Piagentini wrote in the Post.

The outlet reported that Bell's latest appearance before the board was his eighth since 2012.

"The PBA is trying everything with this decision to have it rescinded," Piagentini said.

It is unclear when Bell will be released.
