#AbolishNCR: A Qualitative Analysis of Social Media Narratives around the Insanity Defense

This article presents an analysis of social media posts by laypersons regarding a finding of Not Criminally Responsible on Account of Mental Disorder (NCRMD) for Matthew de Grood after a high-profile trial in 2016 in Canada. From trial to verdict, a total of 4,991 tweets relating to the case were harvested from Twitter. Qualitative content analysis of 365 tweets by laypersons revealed three themes – largely equating the insanity defense to a legal loophole: (1) The case exemplified a misappropriation of the legal defense (e.g., due to privilege, due to the seriousness of the offence); (2) The perception existed that the NCRMD defence is a miscarriage of justice; (3) Many comments reflected a search for answers and justice. These embodied the ABCs of NCRMD: advocating, blaming, and clarifying. A need for public education about the forensic psychiatric system is evident; misconceptions about the insanity defence appeared pervasive. Further research could focus on the efficacy of knowledge translation over new media channels, such as Twitter.
