Here's a good use of GPS: its a new device that allows victims of domestic violence be aware of when someone they have a restraining order against is nearby.
It works via a movement-tracking ankle bracelet that the abuser is required to wear. The victim then gets a cellphone-like device that tracks their location. If the abuser comes within a certain distance, a text or call is sent to the victim or the police.
It's a great idea, although it seems like it would be easier for the victim to use an app on their existing phone rather than need to carry a second phone around with them. But in any case, if this keeps them safe, it's worth it. [San Bernardino Sun via TakePart]
