• The court accepted O’Rourke’s testimony that he stumbled on a median incline and his firearm discharged into Grieves’s car following a collision.
• The pursuit originated from an attempted stop for $40 of stolen gas at a Dutton station and escalated when Grieves’s vehicle struck O’Rourke’s cruiser on Highway 401.
• Grieves’s family left the courthouse in tears and his mother said she needs time to process the verdict.
• The Ontario Provincial Police Association issued a statement saying the decision reflects the complexities officers face in dangerous situations.
