> Securus received the data from a mobile marketing company called 3Cinteractive .... In turn, 3Cinteractive got its data from LocationSmart, a firm known as a location aggregator, according to documents from those companies. LocationSmart buys access to the data from all the major American carriers, it says.

Someone with a little money to burn should subscribe to 3Cinteractive or LocationSmart's service and use the data to spam the whole country with texts with the location info telling the recipient they're being tracked. That ought to rile people up and help end whatever practices enable this kind of tracking.
