I think in the original analogy, the actual robbery is just used as an event which may occur without our knowledge. Your analogy is better, the mapping makes more sense.
Something like: The locksmith has made a copy of your keys without notifying you. They could hypothetically use those keys to enable a robbery, but you won't know definitively either way until you find something stolen. But it is a pretty weird thing for them to do, right?
Well, robbery is theft under threat of force, so it would be very hard to be robbed and remain unaware of it.
