Stay out of Rikers

Tell us something we don’t know, governor, about the dangerous and dismal conditions in the Rikers Island jails, scene of vicious attacks on inmates and staff that led this week to the indictment of 29 purported gang members. Better yet, stay out of the mosh pit of politicians demanding Rikers close not in 10 years, as Mayor de Blasio seeks, but in five years, make that three years, make that yesterday, chasing points in a virtue bidding war.

Not a chance, when Gov. Cuomo smells blood in the water.

Seeing the indictments as a political opportunity, Cuomo counsel Alphonso David issued a statement Thursday demanding “action now” to close Rikers, “on a rapidly accelerated timeline,” while decrying “a savage and inhumane jail.”

Meanwhile suffering a bout of amnesia about violence in the state’s own troubled prisons.

The mayor’s properly cautious plan demands a gradual reduction in criminal defendants detained in New York City to a population that could fit in cells elsewhere, a scheme that will only work if the courts cooperate.

And if de Blasio leads by identifying the sites for expanded facilities near courthouses in the five boroughs — which will then have to be built.

Putting the foot on the gas pedal to radically accelerate the closure timetable risks letting out dangerous people and increasing crime.

Cuomo, who has soundly rapped de Blasio for lapses in handling mass transit and child welfare and homelessness, should think twice before he leaps from the high ground into a mob.
