New York City police commissioner: "We will keep the Jewish community safe"

New York City Police Commissioner Dermot Shea was sworn in earlier this month after rising through the ranks over 28 years. Shea joined the NYPD in 1991 as a patrol officer in the Bronx. The city that year had more than 2,000 murders. In 2018, that number fell to 295. Commissioner Shea joins “CBS This Morning” to discuss the latest attack on a Hanukkah celebration in New York, security surrounding New Year's Eve celebrations, and the stabbing death of college student Tessa Majors in a Manhattan park.
