Yes, absolutely.
As a complaints manager, I handled complaints that were referred to us by the external committee. These complaints were investigated internally.
In all honesty, I have found that police officers and RCMP members are often harsher on their own colleagues than an outside agency would be. At the same time, there is this perception of independence that needs to be maintained.
I would add that this puts police officers who have to investigate a colleague in a precarious position, because eventually they may find themselves working with that colleague, and even being under his command.
There should be a totally independent body, much like the Police Ethics Commissioner in Quebec or Ontario, who is totally independent. The same should apply to the RCMP.
