In any case, the freedom of the WT means that they are free to scam, manipulate, stick their noses in people's private lives, and stalk, slander, and otherwise complicate the lives of people that chooses to leave their spiritual hell by interfering with all relations they formerly had and by creating uncomfortable situations at school or work, or wherever it is they have the bad luck of meeting them.

Personally the only reason I can think of as to why the american government allows their freedom to continue undisturbed, is because somehow they must be benefiting from it.
We can be grateful that they are not allowed to stone apostates as it was done in the old days in Israel. Still socially excluding somebody and separating them from all former friends (even if they happen to be drones) as the WT does is a form of abuse. http://www.youtube.com/watch?v=xn6kmhNdcYg
