Episode 9 code phrase "The crowd does not lie"

I think that phrase "the crowd does not lie" can be utilized in the technologies that we have on hand. If one were to use their twitter account, facebook or other networking sites to report immediate problems the urgency would be evident to others as people report personally on what is happening. You can have one person saying something and it might be wrong but if a mass of people in separate areas are saying the same thing then you can pretty well bet it is true.
