Sketch of the model.

Currently quiescent (active) citizens are represented by blue (red) cells, while LEOs are represented by black cells. Yellow cells show the Moore neighborhood for an agent. Green cells show a vision of radius 4 for the citizen (blue cell). During a move, an agent inspects every cell within its vision radius (green). If there is a preferential gathering site in the vision radius, then the active agent moves in his/her Moore neighborhood in the direction of the closest site with probability (in a simulation, is fixed at either 0%, 25%, 50%, 75%, or 100%). Otherwise, an agent picks a random cell in his/her (Moore) neighborhood and, if the selected cell is unoccupied, he/she moves there; otherwise the agent stays put. Pink cells show a vision of radius 4 for the LEO (black cell). The LEO can intimidate the nearest active citizen in its field of vision (in this model, with probability 1). If there is no active citizen, then the LEO moves to a random cell in its Moore neighborhood in the same manner that a citizen does. The citizens calculate their state depending on conditions on the lattice within their field of vision.
