In the Chilliwack case, a man suffered serious jaw injuries and was jolted by a Taser three times during an arrest after police responded to a man-with-a-knife call.
In the Prince George incident, police chased a driver and passenger on an ATV that crashed into the police cruiser, seriously hurting the passenger.
Vancouver police won't be charged after chasing a man through a steel fence with a police vehicle, sending him flying six metres and resulting in significant leg injuries.
