While I am suspicious about what Walker’s personal definition of what Amnesty really means to him and want to hear more specificity from him. There is a lot of misinformation about him and downright journalistic dereliction going on with respect to him.
In this case, all colleges and universities are required by the Jeanne Clery Act to report violence on campuses (or around them when nearby) in seven different crime categories (sex offenses among them). Enforced by the US Department of Education. So it is very reasonable that a system might try to streamline duplicate efforts.
The university itself asked Walker to delete the sexual reporting as it was duplicative.
