Final answer:
'Specters' can be dangerous to use as evidence because they are not reliable or verifiable sources. Their existence is based on belief and personal experiences, rather than concrete evidence. Therefore, relying on 'specters' as evidence in a factual or legal matter can lead to false conclusions.
Step-by-step explanation:
'Specters' can be dangerous to use as evidence because they are not reliable sources. 'Specters' refer to ghosts or apparitions, which are supernatural entities. They cannot be scientifically proven or verified, and their existence is based on belief and personal experiences. Therefore, using 'specters' as evidence in a factual or legal matter would not hold up to scrutiny and could lead to false conclusions.
