From a JW perspective, I think the game he was playing was a tad immature IMO. I think he was lying about the letters which means he was soliciting this type of response for his "documentary", he should have been more mature. The "Holy spirit" guiding the elders which in his mind equals infallibility, this is over-simplistic. The ELder admitting to the fella that it is possible a mistake could have been made was a nice gesture so I thought the fella was wrong and argumentative. It sounded re-hearsed, which is sad. It is kind of funny that the elders had no problem being filmed for this, makes me....maybe 20%..... sure it was a fake done with a couple amateur actors. However the Elders could be real and could just be real stupid.
Anyway, I agree that the Elders should not have worried too much about a fella who did not care enough to explain his position, unless he was openly causing a major disturbance in the congregation, they should have just forgot about taking any action and let him be. .
