Perhaps I condensed my answer too much. I was trying to compare the commissioner to a business owner, who is in charge of making the necessary decisions. If there's a bad apple, as they say, and someone poses a problem from the RCMP's perspective, then the commissioner must assume his responsibility.
That system applies in every other police force in the country. The commissioner has the absolute authority to suspend someone without pay and get rid of the problem officer. By the same token, the dismissed officer can file a grievance, which goes before an independent tribunal.
