“…This argument, however, does not withstand empirical scrutiny, as a growing body of research indicates that racial and ethnic differences exist in cues of suspicion that officers are trained to identify when determining whom to search. For example, social psychology and cross-cultural communications research suggests that normal nonverbal communication styles among African Americans are more likely to be identified as "suspicious" by both laypersons and police officers (Fugita, Hogrebe, & Wexley, 1980;Fugita, Wexley, & Hillery, 1974;Garratt, Baxter, & Rozelle, 1981;Ickes, 1984;LaFrance & Mayo, 1976;Smith, 1983;Vrij, Dragt, & Koppelaar, 1992;Vrij & Winkel, 1991;Winkel & Vrij, 1990; for review, see Engel & Johnson, 2006). Research on consumerism and marketing has revealed cultural differences in style of dress, vehicle preferences, and recreational travel practices that could cause non-criminal behaviors by minority motorists to be interpreted as clues of drug smuggling (Brown & Washton, 2002;Connors & Nugent, 1990;Remsberg, 1997; for review, see Engel & Johnson, 2006).…”
