I do recall the question. We had a rather well-documented chain of command for the protection of the summit site. In our integrated security unit, we have a number of people on the ground, our operational commanders on the ground, who are out on the street and who have the ability to make decisions based on what they're observing.
In the summit site, that was managed primarily through the unified command centre as led by the ISU. On the streets of Toronto, most of that command work came back through our major incident command centre.
The persons in charge of the major incident command centre are employees of the Toronto Police Service. They're my people; they were superintendents. They're extremely experienced in dealing with large incidents and public order incidents. Two of those officers, each working 12 hours, day and evening, were responsible for running our major incident command centre.
When you asked me about the chain of command, it really depends on which events. Some is related--
