My inclination would be to say that if it's something evidently criminal, which I believe you're talking about, that it would be quite reportable. The only analogy I can think of, and it doesn't fit terribly well, are infrared sensors in geostationary orbit watching for missile launches. They occasionally find forest fires and report them. To me it's a fairly likely event.
