Maybe Pope Francis will say something on his visit to the US, maybe he'll rebuke Donald Trump and anti-immigrant racism and demagoguery beautifully, in a way that illuminates hearts and makes people begin to turn away. That would be miracle enough for me.

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?"

I'm not a Mexican writer, but I think everything that happens in Mexico affects the Mexican writers I know, in their sense of being human and of being Mexican, even if they don't in any explicit way address these issues in their writing.

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 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.

Interviewing is in some ways the art of memory.

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.
