Canada has taken a big step into the 21st century by being the first to finally recognize that work-related emotional trauma leading to the suicide of a police officer can be considered "in the line of duty."

In the US, police agencies continue to stand fast in refusing to acknowledge that work-related trauma and PTSD can lead to suicide. Of 141 police suicides in 2008 and 144 in 2009, not a single one was attributed to the job. There are cases that cry out to be recognized.
Perhaps our brothers and sisters to the north have given us pause to think.
