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

No other agency is scrutinized like the police. Everything we do is in a goldfish bowl. We are not the most popular people in society. We do things like use deadly force; we're the bearers of bad news. We're not firefighters, who are viewed as heroic, helping people, with people loving them back. The police have a much more complex and demanding job.

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 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 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.

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