“…Arrest rates from data collected in the l970s and l980s were generally in the 7% to 15% range: for example, 7.3% (Dutton, 1984, based on the six observational studies he examined); 7.5% (Holmes & Bibel, 1988 in Massachusetts); 10% (Worden and Pollitz, 1984 from an examination of police/citizen encounters in Rochester, N.Y., Tampa-St. Petersburg, Florida, and St. Louis); 13.9% (Bayley, 1986 in Denver, Colorado). More recently, however, these rates have been observed to be 30% or more: see, e.g., 29% (Bourg & Stock, 1994 in South Florida); 33% (Mignon & Holmes, 1995 in Massachusetts); 34% (Buzawa & Hotaling, 2000 in Massachusetts); 36% (Robinson & Chandek, 2000 in the Midwest and Ho, 2003 in Columbia, South Carolina); 39% (Simpson et al, 2006 in Maryland); 48%, 53% and 76% (Hall, 2005 in three cities in upstate New York); 49% (Eitle, 2005 in 115 jurisdictions with one hundred or more officers); and 75% (Jones & Belknap, 1999 in Boulder, Colorado where an agency overseeing the actions of criminal justice officials had been in place for eight years and the pro-arrest policy contained a mandate that officers not only arrest batterers but also have them jailed).…”
