"Governments hoping to evade responsibility for war crimes and rights abuses are having a much tougher time of it these days. Denying entry to nettlesome investigators is still standard while many places are simply too dangerous to investigate. But even where investigators cannot go, digital technologies can sometimes overcome barriers to investigation. A recent Harvard Kennedy School report published by the Carr Center for Human Rights Policy underscores how various digital technologies undermine attempts to hide abuses and war crimes. Commercial high-resolution remote sensing satellites, some capable of distinguishing objects on the ground as small as 30-cm across, allow human rights groups to document military forces deployments, mass graves, forced population displacements, and damage to physical infrastructure."
