Police levels and crime rates revisited

摘要: Abstract Research on the police–crime relationship generally shows police levels have little impact crime rates.

Using county-level data collected from Florida for period 1980–1998 a multiple time series (MTS) design, this study revisited relationship. sample of large cities, most types at county level. Similar results now been reported in three using similar research designs but different units analysis periods. Due to this, showing no between should be reconsidered.
