> People in South Australia will be forced to download an app that combines facial recognition and geolocation. The state will text them at random times, and thereafter they will have 15 minutes to take a picture of their face in the location where they are supposed to be. Should they fail, the local police department will be sent to follow up in person. “We don’t tell them how often or when, on a random basis they have to reply within 15 minutes,” Premier Steven Marshall explained.

Let's see:

* Forced to download an app by the state

* Forced to jump when the state says "jump!"

* Acceding to the concept that there is a state-sanctioned place where everyone is supposed to be (prison colony?)

* Acceding to whatever punishment the police may decide to mete out for failing to confirm that one is where one is supposed to be even if one is already there

That's the thing with slippery slopes. The farther you go down, the more impossible it becomes to climb back up.
