I'm specifically referring to this certain feeling of sadness, fear, and helplessness that descended on me at the Mexico City protest a day or two after the Narvarte murders. Many of us have grown familiar with that feeling. Every few weeks or so it seems we're hit with some new crime or some new corruption scandal that isn't quite the same as a massacre, but that spawns a feeling of futility and despair in its own way.

The writing that most interests me isn't about narcos or sicarios or police or whatever. It's about the victims and the survivors, and about the suffering and trauma that so many in Mexico and Central America endure, and that is all around us whether we notice it or not.

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 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.

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?"

People in the big rich countries are often extremely dismissive of the small countries. They think nothing that happens there is of any interest or that it matters at all, but, at the very least, with that attitude they miss out on some extraordinary stories.

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.
