Donald K. Emmerson, director of Stanford University's Southeast Asia Forum (SEAF), said elements within the Indonesian military have "a reputation for corruption and brutality" and, in East Timor and Papua, have shown a "willingness to work with what might be called entrepreneurs of violence."

Though he said he could not confirm the presence in Aceh of the Laskar Merah Putih militia, he said, "It would be a worst-case scenario if someone in the military were trying to use militias to help carry out repression."
