Re: the silent filter, I'm reminded of the McLuhan quote:
"Man becomes, as it were, the sex organs of the machine world, as the bee of the plant world, enabling it to fecundate and to evolve ever new forms. The machine world reciprocates man's love by expediting his wishes and desires, namely, in providing him with wealth."
There's also Geronimo's block-letter signature, which for some reason moves me. Sense in it his resigned adaptation to a shifting world and adoption of a new language, after years of resistance.
Why not display a Recent Phone Use option when both side buttons of an Apple device is pressed?
* slide to power off
* Medical ID
* SOS Emergency Call
* Recent Phone Use
Report would be high-level -- has phone been unlocked in last 30 minutes, if so, timestamps showing when it was unlocked, for how long, how many finger taps occurred, etc.
That would give law enforcement a quick indication of whether phone was in use. Of course if there are passengers it could be contested. For more detail, they'd have to subpoena as they do now.
