A new University of Florida survey suggests that police misconduct against female drug offenders may be more pervasive than previously thought. The survey of more than 300 St. Louis-area women who had been charged with substance-abuse violations found that 25 percent of the respondents reported experiencing police sexual misconduct in the form of trading sex for favors. It is believed to be the first systematic study to assess sex trading between police officers and female offenders from the women’s perspective. The findings appear online ahead of print in the American Journal of Public Health.
