Editorial: Surveillance and Mobilities.

The editorial introduces the pieces in this special issue on surveillance and mobilities. It draws out the key themes of the issue, asking: what is meant by ‘mobility’ and why it deserves such a focus; what are the goals and purposes of the surveillance of mobilities; and finally, what are the consequences. It proposes a simple typology of mobilities: ‘what moves’ (body, transactions, and artefacts); and ‘movement itself’.
