Sometimes it is because, even if the chance it's real is slim, the stakes would be incredibly high. One time I thought I witnessed a kidnapping, a woman shackled and gagged in the back of a car. I contacted the police and they very thoroughly and professionally pursued it. Afterwards they told me the two people involved were engaged in sexual roleplay. She wasn't being kidnapped, it seemed kind of unusual (you had to be there) but I would have been irresponsible in not reporting it. On the other hand, they could have been SWATed, and it probably cost my city government five digits. I don't have an answer.
