This kind of error is why you can't rely on the government or law-enforcement being competence enough to handle anything. I understand this happened before all the insane digital violation bills in Canada started popping up, but, this kind of mistake demonstrates why the government and law-enforcement can't be trusted to handle our data. They can't be trusted to even look at the right data, let alone understand it, follow up, or determine what is and is not relevant.
This is not a reasonable or understandable error to make, this is a literacy error, which means someone, or some group, can't read, write, or comprehend. How many legal experts were involved, without anyone asking to verify the username? Why did no legal expert ask why there was no evidence on any of the devices? That alone should have prompted the username verification, which would have completely resolved part of the issue before it started.
As for KiK being able to hand over the data, that's another problem. That problem demonstrates why we need strong client-side encryption, to prevent the grotesquely illiterate from being able to get involved. The government and law-enforce can't make a defence, they've demonstrated a total lack of common sense, literacy, or even responsibility, going beyond this single case. Trudeau used emergency powers, illegally, to arrest innocent and peaceful protestors, while filing terrorist charges, after he refused accountability. Carney and his group of pedo's, are passing laws for digital ID, Age attestation, Identity attestation, secret collection orders, and other nonsense, so they can build up the CP spank bank.
