FOLLOW-UP: Apple Knows Your Heart Rate

This isn't a follow-up in that there's more news on this issue specifically; it's just that another article (Graeme Wood, The Atlantic) regarding prisoners wearing tracking devices as opposed to being stuck in prisons reminded me of what I had written about earlier with regard to Apple monitoring people's voices, faces, distances from devices, and heartbeats. I feel like Apple and its iPhones and iPods (of course, with a lot of the other cool features disabled but with the scary monitoring features enabled) would be the prime candidate for this kind of thing; if they detect that the person has moved too far away from the device, they could immediately alert the police (also, this would work if they detect a different face, voice, or heartbeat than the criminal in question). Heh, heh.
