And then how are things different now from the period you covered in the book to what you sense or what's happening in the border in relation to drugs or cartels, et cetera, at the moment?

Yeah, sure.

So like I said, I started reporting on the U.S.-Mexico border in the late 90s.

And in 2010 is really when the drug war violence really started to take off in Mexico.

And I write about that in the book.

And it was important for me to put that context in the history in the book because...

At the time, it was so confusing and so hard to really articulate what was happening.

In your view, You know, why the extreme level of violence, sort of off the charts cruelty? Is this simply about greed? Is that symbolic? Is it a way to drive fear? Is that people that have become sort of mentally unstable? I mean, what's your reading, reporting and then writing on it now and in the book?
