A former scientologist watched this episode and did a reaction and he said most of what south park made fun of is actually mostly accurate of what scientologist believe.
The "dressing up like batman while you choke yourself" is infamously how David Carradine (Bill from the Kill Bill movies) died, it wasn't the doctors fantasy, its something that actually happened. as for the show Cops, it started in 1989 and ran in the USA until the George Floyd RIOTS scarred the network into cancelling the show in America, it's still producing the show (now in its 35th season) and airing it overseas.
Cops was canceled back in 2020, when all of the police brutality videos started coming to light, but it was just recently, a couple months back, resurrected.
FYI All this is real it's worse than what the episode depicts somewhere in Riverside County they got like a cult compound for their cleansing and punishment never able to reach a higher level they say gives you superpowers but always finds ways to lower your e meter power because obviously no one got magical powers.
Another name for an "E-meter" is an ohm meter (when you flip your multimeter to ohms, you are holding an E-meter in your hand). Everyone's body is different in terms of resistance, so they score you based on how good of a resistor you are 😅
