The country has seen revelations about off-books police interrogation warehouses in the past.

A new lawsuit filed in federal court last month alleges that the Baton Rouge Police Department ran a “torture warehouse” where members of its Street Crimes Unit strip searched, beat, and otherwise humiliated people and then released them, often without their being charged with a crime. Soon after the lawsuit was filed, the FBI opened a civil rights investigation into the allegations of misconduct at the now-shuttered warehouse known as “the BRAVE Cave.”
