This is a huge concern because of the use by law enforcement of the Cellebrite device to download and scrutinize the data in cell phones.
I would be less concerned about the device and more about the laws/rules that allow them to ask you for your cell phone when you are stopped for speeding etc. They should have to have a warrant or probable cause. But it seems like they have neither and are just demanding your phone. But this kind of access, including this Apple list, only works if you turn over your phone to anyone or lose it. Without that, the informations existence is moot since it isn't calling out to anywhere on its own and giving it up
