There is quite a difference between reporting a crime to the police without any legal assistance at all, and doing completely nothing because corporate policy tells to cover it up.
And Watchtower legal dept. would throw individual elders under the bus if that would mean less liability for Watchtower. Given the restructuring of the process on appointing pioneers, elders and managing congregations WT already have shown they like to put the legal liability on individual JW slaves.
Therefore any elder involved in either reporting or covering up a crime should have personal legal representation that doesn't serve Watchtower interest first.
