Fair enough. Now how do they plan on enforcing these rules?

In the United States, evidence from an illegal search can't be used at trial. In Canada, the trial judge has the option to exclude illegally gathered evidence.

It's a problem all right, because the police could arrest someone for littering, find evidence of drug dealing in a phone, and then retroactively claim some suspicion of the latter in order to justify more severe charges.

The technical approach to this would be to clone some existing version control system and have a country's court system run its own equivalent of GitHub, so that police could submit crimes and evidence as they are investigated/discovered but not monkey about with their own records. Of course such a system would not be cost-free, and it would still be open to abuses from both sides.

The version control system you describe was originally designed for text-based code, and would probably impose significant time costs on the officers, and delays on the suspects. Police cameras, which could be required to be turned on at any stop, or before any search/arrest would provide the same information (if the officers were required to state their cause aloud). The cameras could even be set to save 5, 10, or 15 minutes of footage before 'activated', so that the police would not be able to claim they 'were in a rush'. This system could also be automatically activated by a gunshot or other sound.

And what if I have an encrypted phone? Can I be compelled to turn over my password? Or my thumbprint? If I use the equivalent of a dead man's switch that wipes my phone if law enforcement tries unsuccessfully to get in, what then?

There may be case law that covers this, but I am genuinely curious.

I can't speak for Canada, but in the US, if a judge orders you to provide a password, you have no choice. If you don't hand it over, this will result in you living broke forever in a prison—and you got your due process.

"if the cell phone had been password protected or otherwise ‘locked’ to users other than the appellant, it would not have been appropriate to take steps to open the cell phone and examine its contents without first obtaining a search warrant."

It's a win/lose for privacy in Canada.

Obviously, giving officers the ability to search phones without a warrant is a bit troubling. However, the Supreme Court has made it abundantly clear that phones without pass-codes still contain intensely private information, and thus are still subject to privacy implications. It's just unfortunate that this bit narrowly passed. (4-3)

> An individual’s decision not to password protect his or her cell phone does not indicate any sort of abandonment of the significant privacy interests one generally will have in the contents of the phone. Cell phones – locked or unlocked – engage significant privacy interests. - The majority ruling's statement[0]

The way they always have, in court. If the prosecutor submits evidence taken from a phone, but doesn't show the gathering of that evidence falls under the rules, the evidence gets thrown out.
