Yeah, from a logical standpoint it makes perfect sense to change policy to get rid of the 2-witness rule in cases of sexual abuse. I think the issue is that they've worked so hard to make their stance seem biblical, they're digging in their heels because capitualiting now would be to admit that the bible isn't the best standard for justice. Also, from a short-term perspective, it's in their best intrests to conceal the pedophiles in their ranks, as their exposure would have been damaging to the donations coming in from the congregations that were affected. It's coming back to bite them in the ass now, though. When you think that you're backed by the almighty himself, you tend not to capitulate to external pressures as easily.
I have a feeling this lawsuit won't stand if their statement that they were unable to be present to defend themselves is true. There will be a number of appeals, but hopefully in the end they just end up paying more.
Actually, notice the suble use of "Jehovah's Witnesses" in the statement. They are the WatchTower Bible and Tract Society - but they try to shift the focus onto their believers instead of their legally registered and legally responsible corporation.
Maybe they do have a little conscience after all. They can't bring themselves to lie and say that the WTBTS abhors child abuse, since that's definitely not true.
