When Raymond Caissie was charged with the murder of Serena Vermeersch this week, many were scratching their heads as to why someone who was already deemed a high risk to reoffend was able to allegedly add to his list of victims. But Caissie had served his time, put in the 22 years he was charged with for a violent sexual assault. So how could someone who was considered to be a high risk to reoffend not still be behind bars? Should criminals who are a high risk to reoffend be able to walk the streets, even after serving their time?
