In the past, Calgary police would ring in the month of December with warnings of a holiday checkstop blitz, often with attention-grabbing names such as Operation Enough is Enough. From 2008 through 2013, police even staged daytime checkstops, looking to nab those who get into the holiday spirit as part of their work day. There may be no official holiday campaign this year, but Acting Staff Sgt. Dale Seddon of the CPS traffic section says officers are on watch 24/7.
