If Warren Hill is executed by the state of Georgia on Jan. 27, one fact will be incontrovertible: Despite the U.S. Supreme Court’s creation of a categorical bar prohibiting the execution of people with intellectual disability, some states, including Georgia, still do so.

The evidence that Hill is a person with intellectual disability is not subject to serious debate. His school records, interviews with teachers, employers, relatives and friends establish lifelong, documented intellectual disability.
