Noisy investigation

Noisy investigations are used by the Church of Scientology to intimidate, harass, and attack those they see as their enemies. The purpose of a noisy investigation isn't to discover anything particular about the targeted individual. The procedure is to contact friends, neighbors, co-workers, and anyone connected with the target, and tell those contacts that they are investigating crimes by the targeted person. The Church of Scientology usually hires private investigators to perform noisy investigations.

In 1966, L. Ron Hubbard wrote a policy titled "How to do a NOISY Investigation" explaining the procedure:

A memo, reprinted in the British paper "People", said: "We want at least one bad mark on every psychiatrist in England, a murder, an assault, or a rape or more than one.... This is Project Psychiatry. We will remove them."

The Church of Scientology used to openly label their enemies as fair game. Though Scientologists claim that the policy of "fair game" is no longer in effect, critics of the Church maintain that fair game is still practiced today. Detractors of Scientology have claimed that the cancellation of the policy only cancelled the use of the words "fair game" but did not change the actual practice.
