Pandya hypothesizes that the aggressive response might have been caused by the sudden withdrawal of those gift-carrying expeditions, which was not influenced or informed by any acts of the Sentinelese. He also notes that whilst the images of the hostile Sentinelese (captured by the helicopter sorties) were heavily propagated in the media, the images of them burying the dead were never released. This selective display led to an effective negation of the friendly images that were circulated in the aftermath of the 1991 contact (which have been already taken out of public display) and restored the 1975 National Geographic narrative.
