I'm not fond of ideologies. I don't like it when people have answers before they know the question.

There's no straight line between closing the mental institutions and filling the prisons but there is some sort of relationship. And it's hard to tell how much mental illness among prisoners came in with them and how much is because of prison. I just imagine the real tragedy is there's probably a huge number of people who went in a little bit f - ked up and left completely insane because it's just a horrible treatment.

If you're willing to give convicts time served and let them walk, why do you want to give them a criminal record? I mean, either they should be in jail, or be free. But it's all because of some internal bureaucratic stat about getting a felony conviction for the prosecutor. Everyone's got their own little game to play, but that prosecutorial part of it is not well known.

These 2.3 million prisoners, somehow we've convinced ourselves that's normal and rational, more prisoners than soldiers, more prisoners than China, more than one per cent of the adult population, seven times the incarceration rate of Canada or any Western European country.

Although I consider myself pretty liberal, I'm not against punishment. There's nothing wrong with punishing someone who has done something wrong. Or with public safety. Lock up a pedophile and there are fewer raped children, but locking up a drug dealer just creates a job opening.

I say a few good things about Canada in the book, you know. Americans are weird, though. We refuse to look at other countries. Start with Canadians - I want to think you aren't that different, so why can't we do our incarceration policies more like Canada? If we still had a 1970 level of incarceration which was the same as Canada's then and now, I never would have written this.

I think there is a lot of crime caused by desperation, and it doesn't mean that people commit crime because they're poor, but certainly a lot of people who are poor commit crime and they might not if they weren't poor. You understand the difference there? That's not news, but it comes up when I hear people say poverty doesn't affect crime - that crime is still going down in America even though the economy is bad.
