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.

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.

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.

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.

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.

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.

I liked the military life. They teach you self-sufficiency early on. I always say that I learned most of what I know about leadership in the Marine Corps. Certain basic principles stay with you - sometimes consciously, mostly unconsciously.
