I'm sure most are familiar with the Greenlee's story floating around the internet. So what if some members of the Governing Body have been accused of molesting a child and used the 2 witness rule to silence a accusation? We would never know.
So could it be that because some high up Watchtower Corporation person/persons has clung to the rule because it save's his corporate ass. I think the reasons for this stupid financial move to stick to the 2 witness rule which is gonna cost them big time in the courts for damages lawsuits is because some very high ups have a lot to lose in corporate benefits.
