“…Homicide statistics, Criminal Justice sources, latest available year, 2003-2008SOURCE: UNODC, 2011a A large group of hypotheses is found in the international literature to explain recent changes in criminality and homicide figures in several developed countries (AEBI and LINDE, 2010;BARBAGLI, 2000;BARKER, 2010;BAUMER, 2008;BLUMSTEIN and WALLMAN, 2006;FOX, 2006;HAGAN, 1994;HAGEDORN and RAUCH, 2004;HUME, 2007;KILLIAS and AEBI, 2000;MORO, 2006;PEARCE, 2006;RENNISON and PLANTY, 2006;RODGERS, 2006;WALLMAN and BLUMSTEIN, 2006;WILKINSON, 2005;ZIMRING and FAGAN, 2000). As is usual in Social Sciences, no consensus can be verified among the authors about the capacity of these hypotheses to explain factors related to the evolution of criminality and homicide/assault, an opinion shared by Tseloni et al (2010). Farrell (2013 singles out and analyzes 15 of those hypotheses related to: "…lead poisoning; abortion legalization; drug markets; demographics; policing numbers and strategies; imprisonment; strong economies; the death penalty; gun control; gun concealment; immigration; consumer confidence; the civilizing process; and improved security."…”
