A process for displaying crime deterrent effects includes first receiving patrol route information indicating a patrol route taken by a law enforcement patrol and determining a type of the law enforcement patrol. Subsequently, a deterrent effect parameter associated with the law enforcement patrol is determined as a function of the determined type of the law enforcement patrol. Finally, an electronic display is caused to display a cartographic map of a geographic area at least partially including the patrol route taken by the law enforcement patrol and, along the patrol route taken, to display a deterrent effect indicator having a radius, width, size, and/or fade time that varies as a function of the type of the determined deterrent effect parameter.
