How the Wisconsin Center for Investigative Journalism investigated prison-abuse allegations

The DOC, citing security reasons, denied the Center’s requests to interview inmates and take photographs in the segregation unit at Waupun, or videotape an inmate at another facility. It redacted from the released records references to inmate injuries and the physical or mental health treatment they received. It categorically denied access to formal complaints filed by inmates against guards, although some released records do convey the inmates’ perspective. And it denied access to video recordings to various incidents, saying this would compromise security.
