If you are judging a single action from someone it is impossible to distinguish between "dishonest behavior" and "stupid behavior" (that's assuming you disagree with what they did), so more offen than not you need to dig deeper and compare what they said prior to the incident and what they have to gain with a change. But to make it clear: it doesn't mean that you are wrong (if what they said align with what you believe, it just means that some people are trying to get the same thing you want for other reasons).
