I don't impose political responsibilities on my fiction. The last thing I would ever want to do, for example, is write a novel that would appear to want to tell people what to think about the immigration debate, and I would never write a novel whose sole ambition was to give a "positive" view of immigrants. I'm for open borders, by the way - down with the nation state!

I think everything you are, everything that engages you, eventually comes to bear on the novel you write. I think the creative energy in novel writing, obviously, comes from tension. From trying to fuse. From trying to make coherent disparate things that might not at all seem to belong together within a narrative.

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?"

Someone wrote in the New York Times recently that if Donald Trump was allowed to go through with his plans, he'd become one of history's major human rights violators and ethnic cleansers, just below the Adolf Hitler and Joseph Stalin league. But people don't care. Trump goes on Jimmy Fallon's show and that spineless puff of a talk show host praises Trump for being such an "off the cuff" talker and providing "fresh air." Fresh air! What's fresh about racism? it comes out of the darkest dankest rottenest human cellar!

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.

Narco fiction novels have a reputation, at least here in Mexico among some of the writers I know, of being somewhat rushed productions, usually written in one way or another like crime thrillers, with something cheesily exploitative about them. It feels exploitive - taking this horrible and ongoing tragedy and trying to turn it into something entertaining. Or trying to turn it into something that might earn the writer a reputation of the sort that many writers believe they aspire to. Or earn them money.

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.
