Gemstone Fileとは 意味・読み方・使い方

The Gemstone File is a series of documents by the American writer Bruce Porter Roberts (1919–1976). The best-known document is probably the 23-page "A Skeleton Key to the Gemstone File", written by Stephanie Caruana in 1975, which presents a brief, undocumented series of claims that conspiracies and suppressed information played a major role in shaping world events since the 1950s. In particular, this document named three individuals as the shooters of President John F. Kennedy, and suggested connections between a number of political assassinations which occurred within a relatively short time frame.
