Experts believe that it is rare for school-related violence to happen out of the blue.  These events are most often carefully planned and developed.  According to Alberta violence threat risk assessment teams, perpetrators leave enough indicators to alert those paying attention, and spotting the signs before it escalates to stop violence before it starts.  The Community Violence Threat Risk Assessment Protocol was signed in Central Alberta this week, in response to recent school shootings.  It’s an action plan that will bring teachers, police forces and social agencies together to spot and flag threatening behaviour in their communities.  Kevin Cameron is the Executive Director of the Canadian Centre for Threat Assessment and Trauma Response, and has been training professionals in these skills for many years.  Kevin says the most important piece is collaboration and communication between all parties, to help connect the dots early and prevent tragedy.
