The Royal Canadian Mounted Police has been using mass surveillance devices known as IMSI catchers, in public, for a decade. In that time, the police have indiscriminately surveilled potentially thousands of Canadians without their knowledge, and stored that information for later use.

Then they retroactively analyzed searches for symptoms of the disease over many months prior to identify patterns of queries most likely to signal an eventual diagnosis.
