Right.

The problem really is (think Andrew Breitbart too) these people have ways of making things seem like an accident.

And they control the media, thus the perception of what happened to you in the event of your untimely demise.

Those two factors along create risk. Unless...the more people out there "in public" exposing these, the better. Strength in numbers. They can't kill off everyone without raising far to much suspicion and creating a Streisand effect.
