"A grave may be shallow. The suppression is not."
A framework for reading any mass-atrocity case file. Five layers, not one. Not depth-in-metres as a spectacle, but depth-of-architecture as a question.
How deep were remains buried?
The literal depth of a mass grave is rarely the deepest fact about it. A shallow grave can still hold a deep accountability failure. Forensic anthropology, soil-layer analysis, and chain-of-custody discipline matter here — not depth-in-metres as a public spectacle.
One site, or a wider geography?
A single named site (Chemmani, Mannar, Sooriyakanda) is almost always part of a larger pattern. The OHCHR Sri Lanka Accountability Project file holds many such sites. The civic question is whether the public can see the geography as a whole, not whether each site is investigated in isolation.
How many years between disappearance, discovery, identification, justice?
Chemmani was named in 1998. Excavations began in 1999. Renewed exhumations followed in 2024–25. Time depth is the gap between when families knew, when the public knew, when the court ordered, and when accountability moved. The wider the gap, the deeper the suppression.
Which institutions delayed, failed, denied, controlled, or stayed silent?
Mass-grave casework moves through courts, magistrates, attorneys-general, OMP, police, military, ministries, foreign offices, UN mechanisms. Each can advance, delay, or block. Institutional depth is the architecture that decides whether a name gets to a family — and the Institute's Live Accountability Dashboard tracks behaviour at each layer.
How long did families carry the truth privately before the world listened?
The deepest layer is usually the one no document holds. Families of the disappeared in the North-East have carried names, photographs, and dates privately for decades. Memory depth is the civic debt — the time a community kept the record alive in homes and schoolbooks while public institutions delayed. The Witness Pledge belongs to this layer.
At Chemmani, the grave may be shallow, but the suppression is deep.
