I think that's a great idea. I for one want to enable our governments to track down criminals and punish them for it. If they're not doing everything they can do so in this technological and digital age, then they are breaking their part of that pesky "social contract" I am being upheld to.
And to people like you that oppose this and propose even more authoritarian laws that prevent me as a citizen from protecting myself: You don't speak for all of us.
Do you see any drawbacks with giving our authorities total information about you me and everybody else?
Perhaps potential for misuse?
Because as I understand the world, the people who hold the most power are generally not the best people.
What do you plan to do when definitions of crime start getting fuzzy? Crime is not just petty crimes where it's a clear cut to tell if someone did something bad in definitive terms.
Other crime types exist that are crime only within a structure. The crime of sharing copyrighted files is a crime within a framework of intellectual rights but then training AI on the same files and and producing alternative files bypassing the IP is not a crime. Then you get into political crimes, i.e. it can be a crime to deny the Armenian genocide, denying the Jewish genicide and protesting against the extermination of the Palestinians at this very moment. It can be crime to hide from the US embassy that you are not completely in support of extermination of Gaza people. Your government might cut a deal to save Greenland from US invasion that makes certain things a crime that the current US administration doesn't like.
This all can change as politics evolves. Do you intend to support whatever the current position the current government has?
You speak as if there is a perfect equivalence between morality and law, and that every action that can be done to increase the rate at which crimes are solved is a good thing. I think that is a bit simplistic and naive.
