The testimony of the director of the RCMP Operations Research group.
Who is on trial for allegedly trying to sell internal Canadian government investigative documents to the CEO of Phantom Secure, the 'secure' communications app popular with the underworld until it got rumbled and who needs some explanation for why he wanted to communicate via a privacy-focused open email service.
We can all speculate. An alternative would be "he's got nothing left to lose and wants to expose more secrets".
I know very little about the case, but how would disparaging Tutanota help his case in this scenario? And why would anyone in the intelligence field need to justify using a privacy focused service?
"I did not use the privacy focused email service for my conversations with criminals because I wanted to sell classified material without being surveilled. I used the privacy focused email service to make it easier to catch these criminals, because it's very very surveilled! A reliable source once told me this. No you can't meet her, she lives in Canada^W undisclosed location. Not guilty, your honor."
