In the late 1990s, a protracted armed conflict between the Indian government and the insurgent organization, United Liberation Front of Asom (ULFA) in the Northeast Indian state of Assam escalated to include ‘secret killings’ of family members, close aides, and sympathizers of ULFA among its many violent manifestations. The killers primarily targeted insurgents’ families to persuade their underground kin to surrender, and to create fear among community members who sympathized with the movement or sheltered its cadres. The 2007 report of the Justice K. N. Saikia Commission pointed out the role of the surrendered insurgents, and the state police behind the secret killings, where the army was kept in the loop in some cases. Surprisingly, over 300 people were killed between 1998 and 2001 under common circumstances but no one was convicted. This article describes the challenges I faced in conducting ethnographic fieldwork on this sensitive event, which continues to draw political and media attention in the region. I focus on the challenges of interviewing survivors, families of victims, and police officers about the secret killings in Assam. I particularly reflect on my fieldwork experience of what to ask, what to write and what to censor about my participants, and consider the ethical dimension of making those decisions. I argue that these decisions were often made spontaneously in response to emergent situations and my ethical principles. I let the responses of my participants guide me in the field, and did not carry any predetermined strategies to guide the interviews.
