I'm a little skeptical of so-called narco fiction, I have to say, though some writers I admire may have written some narco fiction. You feel the dread and the atmosphere in Yuri Herrera's extraordinary novels, but you'd never say that what he writes is narco fiction. The same goes for Martin Solares's novels, inspired by the nightmare city of Tampico, where he's from. Valeria Luiselli, Álvaro Enrigue, I know that they're deeply affected by what goes on in Mexico, but their wonderful writing points in another direction, though not necessarily always and only.

The Peña Nieto government is not going to investigate itself; there's no true autonomy in the investigative and justice branches of the government in Mexico. The recent Mexican crimes and scandals, is profoundly structural, and you'd have to change the way Mexico is run, create a truly independent special prosecutor's office, to even have a chance to get close to achieving justice. People, including the families and many others throughout Mexican society, aren't going to give up in fighting for just that kind of change.

There is a culture of corruption in many parts of the Mexican media, of course. It seems that there are fewer and fewer media outlets that permit authentic free expressions. But Mexico also has extraordinary journalists who, despite the dangers they face, have also been leading the way in this battle, who've really played a role in keeping the cause of justice alive in the Ayotzinapa case. And no matter what, they'll keep doing that.

I'm not against anything that anybody might want to try to pull off in fiction. Fiction writing has to, at least, always represent a possibility of absolute freedom.

I feel a responsibility, as I get older, to be responsible to what I've experienced, to what I've lived and been in a position to witness. I realize now that as a consequence of having lived the life I have, quite apart from the one, as I understand it, lived by most American writers, maybe I now know some things and have some stories to tell that others don't know about or wouldn't be able to tell. Maybe there's an intrinsic value in that lived experience and knowledge, though of course what you do with it is everything.

Mexico just needs more journalists, and especially more good places to publish and exhibit. There are all kinds of censorship practiced in Mexico, not just violent repression. Perhaps the biggest threat to good journalism here is the massive power of the country's media monoliths - Televisa and TV Azteca - who have 80% of the market. They endlessly saturate the country with propaganda and inanity.

I've written one book-length piece of journalism. The Art of Political Murder: Who Killed Bishop Gerardi? That book had an impact. Eight years after it was published it's still having an impact in Guatemala. I remember when I wrote it, a surprising number of people said things to me like, "That is such an amazing story; why didn't you turn it into a novel?"
