Jessie Tisch will be first NYPD commissioner who has served as sanitation commissioner and has been literally been cleaning up every street in the five boroughs. Now, having been selected by Mayor Adams, she’ll be leading a department with 35,000 cops figuratively cleaning up the streets. Thankfully, those men and women in blue have been doing a very good job keeping New Yorkers safe and the general level of crime is historically low (there have been 10 straight months of declines) despite the horror of the random triple stabbing murders this week. But there are always new threats and new dangers to the public and the police that need to be addressed and we suspect that Sunday night will be Tisch’s last fully restful sleep as she begins her new assignment on Monday. While unlike almost all of her predecessors to sit behind Teddy Roosevelt’s desk, Tisch was never a frontline law enforcement officer, she is well familiar with One Police Plaza, having had a dozen years service in the PD, including as a deputy commissioner. It was Tisch who gave every single officer a department-issued smartphone, where each is fully plugged into the NYPD information network. She also revamped CompStat to provide fuller crime statistics for the police and public and implemented the equipping of every cop with body-worn cameras, growing what had been a court-ordered pilot program into a standard part of the uniform along with the badge, handcuffs and gun. Her information advances at the NYPD, including upgrading the 911 emergency call system, led Mayor Bill de Blasio to put Tisch in charge of the entire city’s technology and information agency. Adams, impressed with Tisch, asked her to pick up the garbage and beat back the rats. At Sanit, Tisch has instituted two major reforms for a cleaner city, the collection of organic waste citywide and the use of hard, rat-proof containers. Now, she’ll be working with Adams and Deputy Mayor for Public Safety Chauncey Parker and her chiefs to protect 8 million-plus New Yorkers against everything from terrorists to pickpockets. When Tisch settles in on the 14th floor, she should read the City Charter section which says: “The commissioner shall have the power to appoint and at pleasure remove seven deputies, one to be known as first deputy commissioner.” Clear enough, so why does the NYPD’s web page list 14 deputies (a first deputy and 13 others) twice the allowed number under the charter? Either change the Charter or bring the command structure into compliance. Tisch, a member of a prominent family that’s very involved in the business and civic life of New York, starts her critically important job with the best wishes of New Yorkers to run a department in an efficient and fair manner. Her successful track record at the NYPD and Sanit bode well. When she was at NYPD, we remember Tisch telling us that when she was just graduating law school in 2008 and unsure whether or not to accept a job at the NYPD, her dean told Tisch she should definitely take a job working under Commissioner Ray Kelly at the NYPD. It was good advice. That smart dean, Elena Kagan, is now on the U.S. Supreme Court. And Tisch is now the commissioner.
