Such a position as OSA never existed whilst I was in Scientology but sounds fascist like the Nazi SS or a security set up The former South African secret police was known as BOSS or the bureau for state security. All of these types of positions tend to deal with a purpose with security. The protection police in the name of a bureuacracy. Iraq is having problems with an American security company Black Water. People involved in security can tend to believe they can do as they please with the justification of the protection of whatver group. Security is a very big business especially in the field of crime prevention & is aligned to police services. Intelligence services are all involved in security & protection in whatever context of their operations. LRH seemed obsessed with security always having written to the FBI reporting on his enemies & about other matters that had him labelled by such service as mental. Covert operations are undertaken by intelligence services that Scientology complained about when it was felt they were investigating them but tends to believe it has the right to operate in such context against others.
