I know crime exists, I just don’t think it is so prevalent that we should poison our lives with paranoia and lack of privacy. I’d rather my kids raised on freedom and self reliance.

But these are personal preferences, I’m not imposing this on anybody.

Sure there are trade offs, and your position is understandable. Self reliance and freedom are important but I don't see the value in not being able to call for help when help is needed.

As a parent you can still make the decision to not pick your child up if they are tired and want to be picked up.

I don't see how a wristwatch tracker would have helped, though. Nowadays I'm sure potential kidnappers are well aware that kids often have some kind of tracking device on them (smartwatch, smartphone, AirTag, etc.), and will quickly get rid of any such devices before taking an abducted child with them.

It would have helped because I was walking home from my music lessons. My dad was supposed to pick me up but he was late. This was before cell phones were widely available and I was about 10 years old.

Predators don't just snatch you up like in some movie, they watch their targets first, or lure them away.

People/children have a gut feeling when something is not right and can call for help.

Will it be 100% effective, no, but it will drastically improve response times just by knowing the exact/last location.
