Fear vector management

From Global Guerrillas 

The triple suicide attack on the Palestine hotel in Baghdad is an interesting new example of Fear Vector Management. Chris Allbritton puts an interesting twist on this:

This means they knew where the cameras are. They know how to get into the compound. And there’s a good chance the first two explosions were designed to get journalists’ attention, draw them to the windows and then explode the third one.

If they knew where the cameras were and how to get inside, then they must have people inside. Thus they are invisible to the US occupying forces.
