I think there's not one answer but several answers to that question. I think certainly over the last eight years or so, much of this has arisen in the context of the war on drugs. That's true, but we always have to remember that it's not only about the war on drugs—though certainly many of the cases are.
One piece that was very central was that a number of years ago the Mexican government gave the military rather than the police responsibility for fighting the so-called war on drugs. We obviously already had concerns about many of the abuses being carried out by the police, but things escalated dramatically when the military took over, because suddenly for them it became a war. Everyone was an enemy. Everyone was a suspect. All that mattered was getting bodies and investigations and making the numbers climb to be able to show the Mexican public that they were making progress.
Ángel's case is a very dramatic example of that, but we know of many, many others like that resulting from massive sweeps or from someone being in the wrong place at the wrong time. Or, as in Ángel's case, there were situations aggravated by racism and discrimination. There's no question that racist elements in the Mexican police and military looked at Ángel and refused to believe that a black man could be anything other than a drug dealer, and proceeded in that respect.
The one other thing I would highlight—and I'm sure Ángel and Luis will have other points—is the impunity that has been the norm for so long. This is a reality around human rights violations in many countries, not just in Mexico. But certainly the fact that for so many years in the face of these kinds of cases there has been no justice, no accountability, and no consequences only deepens rather than diminishes that impunity.
