US Government: Guards may be responsible for half of prison sex assaults
It seems that a majority of these  cases were actually consensual, not assault:>Among the substantiated staff-on-inmate cases in 2011, 54 percent were committed by women, the report said. From 2009 to 2011, 84 percent of the substantiated staff-on-inmate cases involved a sexual relationship with a female staff member that “appeared to be willing,” compared to 37 percent of the cases involving male staff members during the same time period.Those numbers imply that overall, 62% of substantiated staff-on-inmate cases were actually consensual. The headline seems inaccurate given that.Of course, there are extreme sampling bias issues with this data. I wouldn't draw any conclusions from it at all.
