We have a lot to celebrate. We have a lot to be thankful for, but our hearts are still very heavy today. Yesterday we lost a good man. We lost New York City Police Officer Dennis Guerra. And I want you to understand what this means in human terms – a married father of four, just 38 years old, a hero, a man who walked into danger to try and save others, and saw it as his duty and his responsibility. We lost someone who exemplified all that's good about New York City, and my heart goes out to his family.
