A broad base of knowledge is critically important to our ability to investigate terrorism.

You're always trying to impress your parents regardless of how old you are. And when they're gone, there's nobody to impress. But I think my parents would be proud of me. My father has been gone for 30 years, and by the time he passed away, I was a lawyer. I hope he would be impressed.

New York is safer than it has been - and it's getting safer. But it's never safe. As the financial and communications capital of the world, this is where terrorists want to make a statement, where they get the most bang for the buck.

Protecting the city is my job, which doesn't translate into hatred. This is war, and in most wars, professional soldiers don't hate the enemy. Hatred can blind you in ways that mar your judgment.

I think it's only natural to want to look good. I enjoy good clothes, so 18 years ago I moved to having custom-made suits. They last longer. They fit you better. In my opinion, I think men don't spend enough on clothes.

Virtually everything I learned about leadership traits and core values, I learned in the Marine Corps. To this day, I keep a list of the traits in a little black book, 14 of them, including integrity, justice, bearing, enthusiasm, endurance - all indicators you aspire to when you're a leader.

It doesn't take a brain surgeon to figure out that if you stop or curtail stop-and-frisk, or if cops are reluctant to do it, violent crimes are going to go up.

When I had the job of police commissioner, 20 years ago, I was more sensitive, more cognizant of complaints and concerned about public opinion. I've learned to do what I think is the right thing. That lessens the impact of criticism. You get used to a pressurized environment and expect it every day.

You can be stopped if a police officer reasonably suspects a crime is about to be committed, is being committed or has been committed. Every law enforcement agency does it. It's essential to policing.
