During each four-hour period, the Smalltown police force requires the following number of on-duty police officers: four from midnight to 4a.m.; four from 4a.m.to 8a.m.; seven from 8a.m.to noon; seven from noon to 4p.m.; eight from 4p.m.to 8p.m.; and ten from 8p.m.to midnight. Each police officer works two consecutive four-hour shifts.
