I'm not denying the existence of false positives. They existed before geofence data and I don't think we have solid evidence on whether they are occurring more in geofence cases than they were before.
I'm not going to debate whether American jails need serious improvement. They obviously do. That's orthogonal to investigative techniques IMO.
I addressed the connection between the two multiple times in my comment. It’s highly relevant we can’t simply trust them with such a powerful tool than inherently includes countless innocent people.
I'm not sure what "two" you're referring to that you addressed the connection between. In any case I think we understand each other and just disagree, and that's fine. All the best.
The "two" are the use of technologies like geofence warrants and wrongful convictions or charges at the accused expense.
Geofence warrants seem too broad to me, providing them with access to people (and therefore probable cause for heavier warrants) merely for passing through an area of a crime.
