good point, exjdub. I know of JWs that are have been trying to collect from the WTS over an injury on WTS property for the last 5 years.
Here in the US, we tend to be a litigious society thinking that is the only means of redress.
I would first concentrate on individual JWs rather than taking on the organization especially in abuse cases. But remember still there has to be documentation that can stand up in court.
If you want to hurt the WTS, if you are attending still, stop donating and find subtle ways to get others to stop.
If you are not still attending, plant a seed of doubt using some of the issues discussed on JWD. Help non-JWs see the true nature of what the WTS teaches so that they can help themselves or others.
