“Understanding the Predatory Nature of Sexual Violence,” David Lisak cites a study in which 120 college men admitted to a total of 483 acts that met the legal definition of rape. Forty-four of those were one-off crimes. The other 439 rapes were committed by 76 serial rapists, who “had also committed more than 1,000 other crimes of violence, from non-penetrating acts of sexual assault, to physical and sexual abuse of children, to battery of domestic partners.”
