You say you are simply the messenger in this type of situation. However, as the commissioner of the RCMP, I assume you still give instructions to your employees.
I will quote from Mr. Campbell's notes to provide some context.
On the subject of that notable meeting, he said:
The commissioner was obviously upset. She did not raise her voice but her choice of words was indicative of her overall dissatisfaction with our work. The Commissioner accused us (me) of disrespecting her by not following her instructions.
He also said:
The commissioner said she told Comms to tell us at H Division to include specific info about the firearms used by [the killer].
You had issued instructions, which presumably were not followed. You were angry or upset about it. You linked it to the conversation you had with the government regarding the promise, or not, to give information about the type of weapons used.
Do you confirm what is in the notes?
Perhaps you were upset about something else, like what you said earlier, or other things discussed at that meeting?
