To be fair, it may have been the owner of the house where the guy was staying who pushed the concubine out into the streets to be gang-raped to death. By the Benjaminites. Which is why the war started where most of the Benjamanites were killed. And all the other tribes swore that they wouldn't let the Benjaminites marry their daughters. Which is why the Benjamanites had to kidnap and rape women, with the consent of the other tribes, in order to rebuild their tribe.

. . . yeah.
