"The irony is that the Witnesses believe the Mosaic law was cancelled out when Jesus came, but they stubbornly insist on enforcing the "two-witness rule." - not only that but the WT always takes scriptures and broadens them out to principles or their own complex interpretations. The GB only care about their OWN image and OWN credibility. THey can't show any scriptures where YHWH wanted to cover up anything bad those he allowed to be in power did, David, Saul, Solomon, etc, he had no problem having dirty laundry aired out.
The two witness rule, if taken on principle, would be applied like this......"in cases such as suspected child abuse, they should be handed over to the authorities who do extensive investigations, examinations, etc, and if there investigation turns of up evidence supporting the claims of the one witness, they count as the 2nd witness" etc.
But they cherry pick what they want to follow and not. They ignore one of the 10 commandments, the sabbath.
