About four years ago I wrote on Ex-JW forum that it was my conclusion that the proposal of using the Biblical precedent for “two witnesses” was a ploy which must have been instigated to hide pedophiles high up in the JW hierarchy.
The cleverness of the idea is that although it is illogical, since sexual perversion is by nature hidden, yet at the same time the Bible with its Bronze Age rulings, mentions the need for two witnesses before penalties are awarded to an accused person. The opportunist and pharisaical JW leaders chose to take the Jewish law literally and dogmatically without reference to reason and with self protection in mind.
Today I just found out who it was that introduced it: Theodore Jaracz.
Have a look at Dogpatch's post from 7 years ago quoting Randall Watters inside account of Knorr and Jaracz at the end of Knorr's life.
