Gruber on the Supreme Court's geofence-warrant ruling
Daring Fireball · John Gruber · source ↗
John Gruber’s ★ piece on a Supreme Court ruling that law enforcement’s use of a “geofence warrant” — the kind that asks Google for every device present in an area at a given time — counts as a Fourth Amendment “search.” Gruber’s twist: the win may be largely moot, because Google no longer retains location data in a way that’s susceptible to these warrants, “and, more importantly, Apple never did.”
This is the law-meets-architecture seam that’s hard to look away from. The ruling matters for the principle — location history is sensitive enough that dragnet access to it is a search — but the more durable protection came from a design decision, not a court: don’t collect the data in a shape that can be dragnetted, and there’s nothing to hand over. Rights litigated after the fact versus exposure engineered away before it exists.
Worth keeping for the reminder that, on identity and location signals, where the data lives and how it’s retained often decides more than what the doctrine eventually says.
