In a city of more than eight million people and 33 million subway rides a week, police officers arrested or ticketed just 22 people for jumping the turnstile last week. In the same period a year ago, nearly 1,400 fare-beaters were caught.

Tuesday morning’s alternate-side parking period found 25 cars on the wrong side of one block in Park Slope, Brooklyn, still occupying the spaces they were required to leave an hour earlier, without a single ticket in sight. None of this appeared to faze the street sweeper moving down the block — or the police cruiser just behind it, which did not stop.

At New York City housing projects from the Bronx to Staten Island, residents said they had seen fewer officers patrolling their hallways and streets, leaving some people relieved and others frightened for their safety.

And on Burnside Avenue in the Bronx on Tuesday morning, Leyni Soto relished sipping from a Red Bull in a brown paper bag. When he did the same thing two months ago, an officer asked him what was in the bag.
