Just have to throw this out there.
In the movie Erin Brokovich, when Julia Roberts(Erin Brokovich) is starting her research on the **chromium** which is contaminating the town water supply. Erin is asking people around the town, faculties about the **chromium**.
Someone speaks up and gives her advice **I would not advertise what I was looking for. Evidence tends to disappear when people can smell trouble**. Something along those lines.
Similar things seem to be happening.
