As Alison points out over at Creekside, the record doesn't exactly inspire confidence when it comes to internal probes or police investigating themselves. One of the comments recalls:
Out of 3,400 investigations of police misconduct in Ontario, only 95 resulted in criminal charges, only 16 officers were convicted, and only 3 actually spent any time in jail.
As with Robert Dziekanski, the officers lied even though they knew there was video evidence.
