You could see that as a lack of detail of the problem as posed. Alternatively it's a breakdown when applying it as an analogy. Time critical scenarios are one possibility. In a safety critical scenario intermittent sensor failure might be possible but keep in mind that consistent failure is too. A jury scenario is presumably one of consistent failure. There's no reason to expect that an intentional liar would change his answer upon being asked again.
