All excellent questions for the defense to ask at trial. Right now, LE hasn't given us any of them.
In practical terms, there seems to be streets and sidewalks with all residences and no commercial buildings between the community center and the condo. Not quite the same as parking at Sonic. I'm sure there are cameras all along the route in Colorado, but once crossed into Utah it gets a little less population. Like it falls into the Category of "little or no" population. Then you hit the strip from Castle Gate through Salt Lake City to Tremonton, Utah, fondly referred to in the west as "the Construction Zone". There's a few short miles of farmland, and then the Great Idaho Lava Flow. It's kind of like driving through a Hawaiian volcano, except the lava is all cooled. Lots of cameras. but they're mostly in people's hands. There is a very popular rest stop in that stretch, but it's huge. I wonder how many black cars stop per hour? One hundred? Two hundred? I just can't wrap my imagination around a realistic number. It's optional to wave at Pocatello as you zoom on past it, then pretty much nothing but a lot of traffic until the turnoff to Hansen. If the defense got someone working on it right now, they would find at least one camera on that route that LE didn't think to check, by the time trial comes up. IMO
