Yes, you read that right: they’re putting the GPS trackers on the *victims.*
Now, it’s not quite as bad as you might be thinking. In fact, on a certain level it’s a good idea: the system alerts the victim if the person who assaulted them, who is also wearing a GPS tracker, comes within a specified distance. But… there is a more obvious, less distressing way to go here: instead of tracking a monitor strapped to the ankle of the victim, just track their *phone.* These days it’s a reasonable assumption that just about everybody has a GPS-equipped phone of some type and keeps it near them. If the villain gets too close, the victims phone starts going buggo with warnings and text messages. Perhaps authorities would even call or Skype to speak to the victim and warn them and check on them. No answer, or a lack of the proper code response, and the cops are sent to apply a beatdown to the villain.
