Talking about TWI now:
In Ohio, the location of The Way HQ, having sex with someone who is incapacitated is rape. Wierille's victims who were incapacitated through drugging were raped. It's straightforward. Some victims complied under the threat of dire consequences if they didn't. Threats were made to the effect of ruining people reputations, careers, families and who knows what else. Sex by coercion is rape. Wierwille and Martindale used their positions of authority to persuade others to have sex with them. In Ohio, this is defined as rape. Others who were not sexual victims, but knew what was going on, were sometimes threatened with physical violence to silence them.
They used the business (TWI) as a vehicle to willfully commit illegal acts. Some might put that in the realm of racketeering.
