  We propose an extension of the Davies et al. model, used to describe the
London riots of 2011. This addition allows us to consider long travel distances
in a city for potential rioting population. This is achieved by introducing
public transport networks, which modifies the perceived travel distance between
the population and likely targets. Using this more general formulation, we
applied the model to the typical Griffin and Ford pattern for population
distribution to describe the general features of most large Latin American
cities. The possibility of long-range traveling by part of the general
population has, for an immediate consequence, the existence of isolated spots
more prone to suffer from rioting activity, as they are easier to reach than
the rest of the city. These areas finally made it easier to control the
eventual disorder by part of police forces. The reason for this outcome is that
transport networks turn riots into highly localized and intense events. They
are attracting a large police contingent, which will later extinguish the
remaining disorder activity on the rest of the city. Therefore, working
transport networks in a city effectively reduces the number of police force
contingent required to control public disorder. This result, we must remark, is
valid only if the model requisites for order forces are satisfied: extra police
contingent can be added swiftly as required, and these forces can move around
the city with total freedom.
