This research note outlines a series of questions about conducting research on state violence and human rights in Thailand. Taking as a central problem the recurrence of state violence across regimes both dictatorial and democratic in the 80 years since the end of the absolute monarchy, I argue that the failure to secure accountability for state violence can productively be placed at the center of researching and writing about modern Thai history. Unevenness is common both to the attempts to secure state accountability for state violence and to the available archival and other sources for writing histories of such violence. This research note examines the particular methodological and analytical difficulties and productive possibilities presented by the partial attempts and failures to secure state accountability and the equally partial available documentation of state violence.
