I listened to the arguments, here's my notes live: --

One justice asked petitioner that because 'If you don't want the government to have your location history, you just flip that off. You dont have to have that feature on your phone. so whats the issue?'

They continue to talk about the Terms of Service stating that Google will comply with legitimate government requests. And both the petitioner and justices seem to agree that ANY data would be then up for grabs by the government (without a warrant) if it is stored in the cloud (including email, docs, photos, calendar, business records, etc). Sotomayor points out that the government would need NO warrant to access these records.

The google feature doesn't exist anymore. But in the amicus brief some 30 providers still have features in similar pattern of record storage. 'Google can track you down to 3 feet'. Google had to search "500 million" accounts for the search in question.

Justice Jackson asks why they aren't looking at the case as a 'reasonable expectation of privacy'? The petitioner agrees, and points out that the data is protected by a password. So the data is NOT public.

Probable Cause was an interesting argument. about 90 minutes in. It went by too quickly. The justice seems to say that google's servers are one 'place'. The justice also sees the output of 3 people despite google 'searching' 19 people as the only people who matter.

Responder is leaning heavy into the 'consent' for google to store location history. Is it possible to turn location history off on modern android phones? Responder also argues that because you're in public AT SOME POINT, then your location data is no different than a cctv data pointing at the street. Then a justice interrupts to make the responder say that YES the government CAN perform these searches on anyone it wants any time it wants without a warrant. For example people who seek abortion, or were at a political event. And the responder agrees!

Responder says the email, photos, and docs still need a warrant because they're like your thoughts or mail, where location is different because people are 'constantly advertising' their location to google.

To me, the responder is arguing two things:

1. That whatever you do in public is always available without a warrant

2. Your location history stored in google (or others) are generated in public and are therefore don't require a warrant.

Responder says location records are records google creates on your phone. Justice asks why no one of the 500M people who were searched have complained? (idk, maybe because we have no way of knowing we were searched?)
