A 5-day battery life is useless for keeping track of your bicycle, but more than enough for a stalker to find someone's home.

Would you expect people to sometimes get away with committing a crime like stalking? Yes. Would you expect every single person who commits stalking in this way to always, without exception, get away with it? Of course not.

The uniquity of technology gives real stalkers this nice excuse. How convenient!

How many stalking victims never found out they are tracked because they used Android phones? How many perpetrators just covertly removed the AirTag after the attack? This device allows very clandestine surveillance by anyone.
I'm willing to grant that the number of people caught would be lower than the number of people who were actually successful -- we don't catch every murderer, for example. But isn't there one, just one, example of someone actually showing up? Nobody ever gets caught? Like I said, this is classic urban legend material.
