I finally took time to read the recent Human Rights Watch report on the Philippines. "Scared Silent: Impunity for Extrajudicial Killings in the Philippines" is worth the time, not so much for the analysis, because we've read it already so many times, but for the numerous personal testimonies. The authors interviewed many relatives of the victims. Even if I have read many of them before, and even interviewed some of them in person myself, the sheer number of personal testimonies in the report is emotionally overwhelming and leaves one without much doubt about the involvement of the Philippine military in the killings.
Interestingly, HRW talks about a "dirty war" to describe the situation in the Philippines. Knowing the situation on the ground, I couldn't agree more.
