A thought occurred that the way the society has stigmatised the doing of external research by witnesses, and labelling any such questioning as "apostate", is tragic.
No doubt, in EVERY other aspect of life, we research things before making decisions. eg, if making a purchase, we go online and check reviews etc to check the product out. We don't just trust the words of the marketing department. This is not a sceptical task, but a fact finding one.
Or, what if we hear about a product recall, for example a tinned food in a grocery store, do we take the precautionary step of checking our pantry, and getting rid of any possibly affected item we have bought? Or do we say "I have always bought this item, and I will not change now just because the Media has released a warning!"
Or if a vehicle manufacturer issues a recall to fix a problem, do we ignore it?
