If Jesus Christ were to return tomorrow and expose the WTBTS as not spirit directed and as a dangerous cult, most JWs would behave like the Jews did in the Bible.
IMHO the best way to help JWs (and members of other dangerous organizations) in the USA is to revise the Tax Code for tax-exempt organizations to protect children from sexual abuse, prohibit using and promoting undue influence, and increase transparency and accountability. If you would like to help, read the threads
Revise Tax Code to Protect Children from Sexual Abuse and How to Complain to the IRS about Non-Profits .
Lawsuits will not significantly impact the WTBTS. The WTBTS will just squeeze JWs for more donations. On April 13, 2015, the California 1st District Appellate Court established a policy that religious organizations do not have a duty to warn members about pedophiles, even though an organization's practices protect and enable predators, short-circuits the prosecution of predators, and prevents reporting the location of convicted predators.
Peace be with you and everyone, who you love,
