I hate to say it, in a way, but in light of Parker Well's being lost and loss of life, perhaps it would make sense to provide non-verbal or autistic children with government supplied wristwatch/call help|home/gps tracking devices to assist in search&locate.

Really for anyone of any age. Of course there are already cell phones, but think like life link: call help. Seniors (Alzheimers/dementia), disabled, lost/missing, falls (ie: off a roof) when alone, broken ankle, etc. Any reason really.

International Action Plan

It probably wouldn't help with things like MMIWG and abductions/kidnapping, but with non-nefarious situations, like Parker's, it would start to fill the gap.

Yes, I suppose, animals too, depending on size, battery life and swap ease of use.
