does it work both ways? can i present this data as an alibi when i need one? if its not deemed accurate for that why would it be considered for evidence? and if it is that seems like free alibis for everyone guilty or not ;)
Which do you think is more important? Needing to present an alibi in the case of you being wrongly accused? Or needing to conceal your actions in a world where something new has been made illegal?
The entire millenium-old body of law surrounding what rights you have when dealing with the police exists in order to protect the innocent, not the guilty.
Things like warrants don't exist to make it impossible for the police to do their work. They exist to make it so that they spend less[1] time harassing people who have done nothing wrong. It's difficult to frame the police scooping up data that a third party has on you as harassment.
