There's no dispute that Aurora theater shooter James Holmes is a killer. But is he guilty of murder? Holmes has pleaded not guilty by reason of insanity to murdering twelve people and injuring seventy more by opening fire during a midnight showing of the latest Batman movie in the summer of 2012. The insanity defense is rare in Colorado, and "Mind Games," by Melanie Asmar, examines several instances in which it was used over the past fifteen years in an attempt to illustrate when it works and when it doesn't. "Mind Games" attempts to explain a complicated plea in one of the most emotional and wide-ranging murder cases in Colorado history.
