Republicans in the state Senate moved to tighten the qualifications for winning parole following the release of cop-killer Herman Bell over the angry protests of law enforcement groups.

“I am troubled by recent decisions by the Board of Parole to release people who have committed some of the most brutal crimes, including a convicted cop-killer,” said state Sen. Patrick Gallivan.

“Such decisions are indefensible and an affront to law-abiding citizens. These bills will increase penalties for the most violent offenders, reform the parole system and ensure the protection of our communities.”

Family members of victims would be allowed to speak to Parole Board members deciding on a release, under a measure drafted by Sen. Andrew Lanza, of Staten Island, and passed on Tuesday.

A bill authored by state Sen. Terrence Murphy, a Republican from Yorktown, would prohibit parole and mandate life sentences for people convicted of killing cops and other first responders.

Another piece of legislation, sponsored by state Sen. Marty Golden, a former NYPD officer from Brooklyn, would deny release for people like Christopher Thomas, who killed 10 people in 1984’s Palm Sunday massacre in Brooklyn.

Another measure imposes life sentences for those convicted three or more times for violent felonies like rape, arson and kidnapping.

Yet another bill would require life imprisonment for murder.

“The Senate took action today in order to address recent incidents where the rights of convicted and dangerous criminals were put ahead of the law-abiding public,” a statement from the Senate explained.

“Last week, notorious cop-killer Herman Bell was released from prison, even after he lured New York City police officers Waverly Jones and Joseph Piagentini to a Harlem housing project in 1971 and murdered them both solely because they were cops.”

Senators also cited a pending decision on whether to release Judith Clark, who is imprisoned for the death of two police officers in a shootout during a Brink’s armored truck heist in Rockland County in 1981.

The bills are expected to meet fierce resistance in the Democrat-controlled Assembly.
