In 2013, 44 year-old former drug addict David Sullivan attacked and repeatedly stabbed his elderly mother. In 2015, 19 year-old former high school rugby star Thomas Chan brutally murdered his own father. Both suffered severe psychotic breaks that led to their violent actions, but due to a quirk in Canadian law, both were convicted and sentenced to five years in prison.

The successful appeal of these cases was reported as the court legalizing intoxication as a defense for sexual assault, resulting in a massive public backlash largely unrelated to the ultimate fates of two innocent men.
