Great observations Schnell.
Even the background to his appearance is appalling. The Branch coordinator tried to play down his role and the had their lawyer blindsight the Commission. Fortunately, there were a number of ex JWs able to communicate with the Commission whilst it was in progress and inform them of the true situation. The Commission initially took the word of the JWs and were not going to call Jackson up but when they understood his role, they decided his testimony could be beneficial.
This is partly the reason why Jackson downplayed his role as a GB member.
Then there is the Case where G. Losch was subpoened to appear in a Child Abuse Case. He refused to appear and lodged a Declaration which included this statement
I do not answer to Watchtower. .... Watchtower does not have, and never has had, any authority over me." - Gerrit Lösch in a signed Declaration submitted to the Superior Court of the State of California, County of San Diego, dated February 4th, 2014
The whole Declaration can be found here -
