I still don’t get it. If police gather fingerprints at a crime scene, is that search overbroad because there might be prints from people other than the criminal? I would argue that the ability to search large volumes of data is a plus not a negative. Must police know who they are looking for before they can take fingerprints?

US appeals court rules geofence warrants are unconstitutional

… But critics have long argued that geofence warrants are unconstitutional because they can be overbroad and include information on entirely innocent people.

… But because the bank of data is so big, and because the entire database has to be scanned, the court ruled that there is no legal authority capable of authorizing a search, per a blog post by law professor Orin Kerr analyzing the ruling.

… The court said in its ruling, its emphasis included: “This search is occurring while law enforcement officials have no idea who they are looking for, or whether the search will even turn up a result.

… Kerr, in his analysis, said the ruling “raises questions of whether any digital warrants for online contents are constitutional.”

Deep-Live-Cam goes viral, allowing anyone to become a digital doppelganger

While the results aren't perfect, the software shows how quickly the tech is developing—and how the capability to deceive others remotely is getting dramatically easier over time.
