The petition for certiorari follows the ACLU’s appeal of Galloway’s conviction and death sentence in the Mississippi State Supreme Court. Galloway was eligible for a capital trial based solely on the scientifically invalid testimony of forensic pathologist Dr. Paul McGarry that the victim had been also subjected to sexual battery. The ACLU appealed Galloway’s conviction to the Supreme Court of Mississippi, challenging Dr. McGarry’s bogus testimony as well as numerous other errors at the trial that violated Galloway’s constitutional rights. On January 24, 2012, several world-renowned forensic pathologists submitted a friend-of-the-court brief to the Mississippi Supreme Court on Galloway’s behalf, demonstrating that the testimony Dr. McGarry presented as fact has absolutely no basis in science. Without Dr. McGarry’s junk science testimony, Galloway would not have been exposed to the death penalty.
Junk Science and Capital Punishment: For defendants facing the death penalty, the admission of unreliable and unfair “junk science” testimony is often deadly. Junk science is presented in many forms, including wrongful testimony from “future dangerousness” experts, often based on race or other traits that have nothing to do with a defendant’s likeliness to cause future harm, or unreliable testimony from experts in medical or science fields about the significance of certain crime evidence.
