On the Down the Hill podcast Robert Ives discussed how difficult the technological aspects of this case had been (leading me to think that LE’s ignorance of technology was the main problem getting this solved JMO)
One point Ives made was that everyone assumed they could get all cell tower records just by demanding them or whatever, but that’s not how warrants work! LE has to be clear & targeted about what they’re looking for & why they think it will be there.
They can’t get a warrant for all nearby cell tower data - that would be like having a warrant that everyone who lives within 5 miles of the crime needs to throw open their front door & LE will walk by & peer in.
My understanding is that usually they can get the general tower data - this has come up in a lot of different cases - but i don't know the law specifically in this state
So basically the general tower connection data is not regarded as your personal info, as compared to needing to get a warrant for your personal customer records....
