They resisted for two years.
Are you ignorant of the facts or are you a liar?
I did say this earlier;
"How is it that the elders for three years refused to cooperate with the police? All the police can do in respects to this matter is ask the elders to make a statement. Whether they choose to make a statement or not, this conversation would take place over the course of a few minutes, not a few years."
If there was any legal objection presented to being called to testify in court, it's because the law is not black and white pertaining to penitential communications in the U.K., as it is in the United States. This is likely because the U.K. doesn't have any reporting laws. There are consequences if anyone does not fulfill a legal obligation, even if it's a small fine for failing to appear for jury duty. If the elders were in no way penalized by the legal system, they fulfilled their legal obligation, pure and simple.
It would be more constructive for you to write a letter to the governor of California and like states pertaining to this matter and voice your complaints, than to complain about Jehovah's Witnesses. They're a minute fraction of the problem if you believe there is one. In the U.S., the law is black and white and because of their confession protocols, Christendom's churches don't even have to report a matter, let alone testify. Because of the protocols and tenets of JWs involving a "third person," they would have to testify under California law.
