The shocking truth about how Scientology really works, according to one former insider

"Leah Remini: Scientology and the Aftermath"/A&E

Leah Remini continued her quest to expose the truth behind her former religion Scientology on Tuesday's new episode of A&E's "Leah Remini: Scientology and the Aftermath."

On the episode, Remini traveled to one of Scientology's major centers in Clearwater, Florida, to visit the home of Mike Rinder.

Rinder was a member of the church for 46 years and rose to the top of the organization as its international spokesperson, a position he held for more than two decades. Rinder shed light on the alleged methods used on people labeled as enemies of the church.

“Part of my job was to discredit and destroy critics who spoke out against the church," Rinder said. "If the church believed that someone was an enemy and needed to be silenced or destroyed, it was my job and I did it.”

Toward the end of his tenure at the church, Rinder had displeased Scientology leader David Miscavige and his only real choice was to leave the church. In the process, his wife and family, all members of the church, turned their backs on him.

“I feel bad for the people who were hurt with my actions," Rinder said of his reasoning for speaking out against the church now. "If I can help one person who I may have harmed in the past or prevent someone from being harmed in the future or a family from being harmed in the future, this will all be worth it."

For the record, the church says Rinder's claims of its alleged abuses in the series are false. It maintains that he was fired from his job as spokesperson in 2009 and expelled from the church, and that he continues to speak out for financial gain.

Here are the most shocking revelations about Scientology's alleged inner workings from the show's second episode:

Scientology founder L. Ron Hubbard was under investigation in multiple countries and lived on a ship to evade any one country's jurisdiction.

Rinder explained that in the early years of Scientology, the church was under investigation for being a cult. In fact, Australia banned the religion in 1965 after its investigation.

L. Ron Hubbard lived on a ship called the Apollo. Binder described it as the “floating headquarters for Scientology.” Since he was being investigated by the UK and other countries, Hubbard found that he could sail away when necessary into international waters and away from the jurisdiction of any one country.

L. Ron Hubbard had his own elite guard called the Commodore's Messenger Org.

The elite group of Scientology members, the Commodore’s Messenger Org, worked directly for Hubbard. They were like an army of personal assistants, Rinder said. Many of them later would move on to running the church.

Scientology had a policy called "fair game" to justify its actions against enemies of the church.

"Fair game" was the idea that anybody who’s an enemy or critic of Scientology can have anything done to them because the means justify the ends, according to Rinder.

Basically, it allowed members to push the boundaries of legality when it came to shutting up and destroying the organization's detractors without fear of punishment from the church.

The church maintains that the "fair game" doctrine has been canceled, but Rinder, Remini, and other ex-Scientologists claim it's alive and well.

Rinder said actions could range from stalking, digging up dirt, checking out people's background, vilifying them in the media and on the internet, and hiring private investigators to surveil them.

Rinder and his current wife claim that Scientology bought the house across the street from them and paid a female investigator to live there. This went on for several months and unknowingly the couple had befriended her. They began to get suspicious when they moved and the woman also moved to the same neighborhood.

Rinder says he then received an anonymous note saying that he shouldn't trust the neighbor. Rinder said he would later discover that a birdhouse the woman had on her property actually held a camera pointed at his house.
