Nothing uniquely bad has happened to me in my personal life, but all the regular little bad things have accumulated to make me a neurotic person. And these adventures are my way of trying to make sense of that.

There's definitely evidence that capitalism at its most ruthless rewards psychopathic behavior. When you look at the worst corners of the American health insurance industry or the sub-prime banking market, it really feels like the more psychopathically someone behaves, the more it's rewarded.

At first, I did stories on people who were maybe just eccentric. Omar was a natural progression from that.

But on the extremist side I didn't get any rejections at all. Everyone agreed to talk to me.

But when I was doing the KKK I had constant nightmares of being exposed as a Jew and lynched by the Klan.

I wasn't in any way a kind of soothsayer or not surprised when Sept. 11 happened. I was absolutely shocked.

I'm not what you'd call a fearless type of person.

My paranoia never ends, but I haven't been paranoid about being spied on my shadowy forces for some time now.

Obviously, I like to write stories that are page-turners. But I always try my very, very hardest to be as factually true as possible.

Success is always less funny than failure.

Trying to solve the mystery is what I enjoy most about writing.

You can say anything to David Icke and he will accept it and put it into his ideology.

Discover the time of day when you write best, and write then. For me it's about 7 am to noon. For other people it's overnight. Try not to do anything other than write between those times.

I did feel like they were telling me that something like that was going to happen. Not specifically - not that planes were going to be flown into the World Trade Center or anything like that - but in the general sense.

I have thought sometimes that the sanest people, the people who are just very balanced, very happy, are probably lower achieving than other people. My kind of irrationality happens to be fear or anxiety.

I think if somebody is so set in their ways about what they feel about something - and you get this a lot in academia, of course, and also different sorts of journalism too - you're going to sweep under the carpet the facts that don't suit your thesis. And I think that happens quite a lot in the courtroom, for instance.

No, people back home don't realize why there is this kind of need for heroes in America at the moment. People in Britain don't really understand what's going on here. They don't understand why Camp X-ray exists.

Of course there are people who would like to eat breakfast without the screams of toddlers all around them, but those people should get over themselves and stop being stuck up and idiotic.

Sometimes labeling is only useful, like with OCD. Once you're labeled you can be treated. On other occasions labeling leads to tyranny, like with childhood bipolar disorder in the U.S.

We have to understand how the extremists got the way they are. Without that kind of understanding, we'd never really get to know them. I put in nothing about their childhoods. But what I have put in is stuff about the weird symbiotic relationship between us and them.
