Isn't that "instruction" incredibly circular logic of sabotage for the sake of "proof" justifting what they already believe because of the outcome they caused?

Isn't that "instruction" incredibly circular logic of sabotage for the sake of "proof" justifting what they already believe because of the outcome they caused? I recall an episode from a fictional crime show where the obligatory twist behind a horrically toxic water pollution blaming a new industrial operation. It had killed three people and sickened more was a radical environmentalist who wanted to frame a factory they believed would pollute more long term. Ironically one of the give aways to investigators was something the industry no longer used.
