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.

I think I've had a long, distinguished career in public service. It just goes to show you what some politicians will do. They'll say or do anything to get elected. I know all these people. They all claimed to be friends of mine up until their mayoral campaigns. They'd call me on the phone and ask for information or come over here and sit in this chair to get briefed.

Good news is not news. Bad news sells. Confrontation sells. And that's what the press is always looking for. I'm not bragging, but I have the highest job-approval rating of any public official in the city. And I've had it consistently. The approval rating for the police department is 70 percent. This notion that stop-and-frisk has torn the community apart is false.

I never think of the word legacy. It doesn't mean anything. You do the right thing, in my judgment, and things will work out. That's what drives me. I'm not looking for legacy or history books or whatever. I know what we've done here has saved a significant number of lives. The burden is not on me. It's on the politicians who made the decisions to limit what we're doing. They're the ones who are going to pay a price, in my judgment, if crime significantly increases.

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.

I've been the longest-serving police commissioner in the history of the department, but it's time in my life to move on. I'm ready for new adventures, new challenges.

If you go into any department store these days, your picture is probably taken 30 times. In London there are 500,000 cameras in public spaces. You have no expectation of privacy in public spaces.
