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.

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.

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.

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.

I think one of the biggest scams in law enforcement is the monitor.

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.

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.
