How about old fashioned criminal litigation? Or are prosecutors and Judges scared too? These people have work camps on their premises where apostates are ‘reformed’.
Lisa McPherson was deliberately starved to death as punishment for imaginary infractions.
The local medical examiner initially ruled the cause of death undetermined (which would legally require a more thorough inquiry), but then changed her ruling and 'corrected" it to accidental.
Everyone in their work camps has signed multiple documents volunteering for duty, and the finest lawyers in California will make sure that any warrants are contested long enough to clean things up before law enforcement gets inside the premises.
These guys have 50 years of collective experience and expertise in gaming the justice system. Few DAs have the mental or financial resources to match wits with them.
