Myopia Theory
Preventative Patrol is a theory of policing developed by O.W. Wilson that proposes that having police cars patrol an area in a “constant, unpredictable motion” can reduce and prevent crime. Larry Sherman’s experiments with the Kansas City Police Department in the 1990s proved that preventative policing can effectively reduce crime—but only if it is applied aggressively to a focused area where crime is known to occur at higher rates. In contrast, preventative patrolling is ineffective when practiced indiscriminately across unconcentrated areas.
