They certainly can and do use a tracking system.
I get notifications from Delta every time my bag moves once it’s checked in - loaded, unloaded, what pickup.
There’s nothing really wrong with barcodes. NFC/RFID would be a logical upgrade though, and just has to integrate into the existing system.
Honestly it doesn’t feel too far to me, and I generally detest doxxing as a tactic.
We trust and depend on journalists to expose and spread the truth and tell the stories people should see, but it’s never supposed to be at the expense or exploitation of vulnerable people. It’s one thing to expose the personal details of say, a hypocritical politician, but putting an individual’s life at risk just to spice up a story seems to violate most journalistic ethics I’m familiar with.
And where these are most popular, the police would choose not to do anything anyway.
