According to the U.S. Department of Justice, there were 194,270 white and 17,920 black victims of rape or sexual assault reported in 2006. However, the report does give a note that for the percentages of white-on-black or black-on-white rape, and the estimate of total number of black victims, the statistic is based on 10 or fewer sample cases.[279] The Uniform Crime Reports includes most Hispanics in the “white” category.[280] According to Anthony Walsh, “Gary LaFree’s rape data for the 45-year period revealed that blacks were arrested for rape an average of 6.52 times more often than whites.”[280]
