As far as the government scientist was concerned, it was a bit of fluff: an early morning interview about great white sharks last summer with Canada AM, the kind of innocuous and totally apolitical media commentary the man used to deliver 30 times or more each year as the resident shark expert in the federal Department of Fisheries and Oceans (DFO). So he sent an email off to Ottawa notifying department flaks about the request, and when no response had been received by the next morning, just went ahead and did it.
