Cory Doctorow's "I, Robot" (novelette, free): When North America was a police state

This is may be the most readable short fiction I've seen from author so far. Suspension of belief becomes much harder towards later parts of the story, but first two thirds is great.

Story summary.

This is the story of Arturo, a policeman in North America ("UNATS"), & his difficult relationship with his teenager daughter Ada. As a consequence of their conflict, we get to see the police state of "UNATS" (North America).
