Caption for the above photograph: "This WIREPHOTO is straight from the newspaper's historical photo archive. Wirephotos are different than traditional photographic prints! This print is the result of what used to be breakthrough technology (now completely obsolete) that allowed a photographic image to be scanned, transmitted over 'the wire' (telegraph, phone, satellite networks) and then printed at the receiving location. They are often on thinner, slick paper (very similar to old thermal roll fax paper) and often fade or become sepia toned quicker than traditional silver halide prints. Long removed from commercial use, these artifacts represent an important era in the history of news media."
Before 9/11, the largest loss of civilian American lives due to a deliberate act was the Jonestown Massacre of 18 November 1978. This pacifist American cult committed mass suicide under psychological duress exerted by their psychopathic priest, Reverend Jim Jones. The cult, the Peoples Temple, had been developing under Jones's leadership for some twenty years prior to their migration to Guyana, where they died after drinking cyanide-laced Kool-Aid. The act passed into public consciousness and generated an American expression describing how someone fully and foolishly accepts ideas which are fatally wrong: "He drank the Kool-Aid."
Before their mass suicide, the cult's guard squad hunted down and murdered an American Congressman and NBC news team who visited them on behalf of cultists' family members. An account of the grisly events is here.
