A point I called out. What I was trying to do was make an argument that we may have begun our journey to "if you don't have a cell phone, you're suspicious". How long until someone could use their GPS tracking data and witnesses on the other end of the phone as an alibi to prove their innocence when the prosecution has a case that says otherwise, except they don't have a mobile phone?
Slipper slopes aren't always that slippery, but sometimes they are. It's just a possibility, and possibilities are fun to think about.
