This article covers Operation Snow White, a 1970s conspiracy by the Church of Scientology to erase unfavorable records about Scientology and its founder, L. Ron Hubbard. The operation involved infiltrating 136 government agencies, foreign embassies, and private organizations across 30 countries, making it one of the largest government infiltrations in U.S. history. It also led to the exposure of another plot, Operation Freakout, and prompted a U.S. government investigation into Scientology.
