I find it concerning that a judge, being presented with a textual description of four GPS coordinates would sign off on a warrant without simply asking... "okay, can you show me that on a map then?"
A judge would sign off given just the list of coordinates, and legally, they'd be correct in doing so.
That is true, but these areas usually do not involve the private homes of people. Police can ask to look around, but if the owner of the home declines, then police have to come back with a search warrant and afaik that warrant needs to be specific to that property.
This is the digital equivalent of that but applied on a whole geographical area, basically a "digital bulk search warrant".
Because I doubt these warrants will surface to the judge how many people will be affected, in a very invasive way.
When you factor in much of our modern lives are saved on servers of Google or Apple, then this is actually a much worse invasion of privacy than just having a couple of unis take a quick look through your home physically.
This is the equivalent of them sitting down in front of your phone/computer and being able to spend hours upon hours on browsing through your private data.
