NYPD Commissioner Bill Bratton told NPR's Robert Siegel that a work slowdown had occurred after all, after denying the charge earlier this week.

"We're coming out of what was a pretty widespread stoppage of certain types of activity, the discretionary type of activity by and large," Bratton said. "I'm very conscious of the impact of all of those on my personnel."

The Washington Post reported earlier this week that criminal summonses, along with traffic tickets, were down 90 percent compared to last year.
