“…The minority-group threat hypothesis has been examined across a number of criminal justice outcomes. This body of research finds that large and growing non-white population size is associated with arrest decisions (Eitle and Monahan, 2009), police force strength (Carroll and Jackson, 1982; Jackson and Carroll, 1981; Jacobs, 1979), citizen complaints (Holmes, 2000; Smith BW and Holmes, 2003, 2014), sentencing outcomes (Nowacki, 2018; Wang and Mears, 2010), and police use of deadly force (Jacobs and O’Brien, 1998; Liska and Yu, 1992; Nowacki, 2015; Smith BW, 2004; Sorensen et al, 1993; Willits and Nowacki, 2014). Fewer studies have examined the link between racial composition and traffic enforcement (see Novak and Chamlin, 2012 for an exception).…”
