Additional details:

> The information that Google provided to law enforcement officials came in three tranches. First, Google gave law enforcement officials a list of the 19 accounts (but without the names attached to those accounts) linked to devices that were within 150 meters of the bank during the 30 minutes before and after the robbery. Second, based on that list of 19 accounts, the government asked for additional information about nine accounts that were in the area during a two-hour period. At the third step, a detective asked for, and received, the names and information associated with three accounts – one of which was Chatrie’s.

> Relying on the location data, law enforcement officials obtained a warrant to search two residences linked to Chatrie, where they found almost $100,000 of the stolen cash, a gun, and demand notes.

> Prosecutors charged Chatrie with bank robbery. He asked the trial judge to bar prosecutors from using the evidence obtained as a result of the geofence warrant at his trial, arguing that the warrant violated the Fourth Amendment.

> A federal district judge agreed that the warrant in Chatrie’s case did not have the kind of probable cause and specificity that the Fourth Amendment requires. However, she nonetheless allowed the prosecutors to use the evidence, reasoning that even if there had been a violation of the Fourth Amendment, law enforcement officials had acted in good faith.

good. Of course the precise language of the ruling matters, but good.

Of course Alito and Thomas would have allowed the government unlimited power. I am bit surprised to see Barret in the minority of this one.

She's not as big on some of the broader interpretations of the 4th amendment that more civil liberty minded justices would lend credence to.

Particularly when it comes to tech, she usually goes along party lines but she's been surprisingly independent in other areas. When it comes to the 4th she does heavily prioritize the sanctity of the home and property rights.

What if they purchase the information from a company peddling it rather than compelling cell phone companies to hand it over?

That is the loop hole IMO and that's how they will get around it.

rare scotus W, but i strongly suspect that because this data is "owned" by someone other than the people that generated it that said owners will simply choose to voluntarily cooperate with government inquiries 100% of the time. You can suppress information if the government unconstitutionally compels google to turn it over, but I don't believe that you as a defendant could push to exclude evidence if it was willingly turned over by a third party that had the right to have it.
