According to the Report on the Surveillance Society for the Information Commissioner by the Surveillance Studies Network (September 2006),
http://www.ico.gov.uk/upload/documents/library/data_protection/practical_application/surveillance_society_full_report_2006.pdf "3.1. Definitions are vital, especially with a controversial word like surveillance. Often thought of in rather specific, targeted terms, in reality it is much more. Rather than starting with what intelligence services or police may define as surveillance it is best to begin with a set of activities that have a similar characteristic and work out from there. Where we find purposeful, routine, systematic and focused attention paid to personal details, for the sake of control, entitlement, management, influence or protection, we are looking at surveillance.
3.2. To break this down:
• The attention is first purposeful; the watching has a point that can be justified, in terms of control, entitlement, or some other publicly agreed goal.
• Then it is routine; it happens as we all go about our daily business, it’s in the weave of life.
• But surveillance is also systematic; it is planned and carried out according to a schedule that is rational, not merely random.
• Lastly, it is focused; surveillance gets down to details. While some surveillance depends on aggregate data, much refers to identifiable persons, whose data are collected, stored, transmitted, retrieved, compared, mined and traded.
3.3. The personal details in question may be of many kinds, including CCTV images, biometrics such as fingerprints or iris scans, communication records or the actual content of calls, or most commonly, numerical or categorical data."
I could go on, but I don't want to spoil the ending for you.
In the meantime, yes, of course we like to know who committed crime in all cases. But why do you make the assumption that a universal NDNAD will deliver that outcome? And do you think that outcome should be pursued to the severe detriment of policies which can reduce crimes taking place in the first place.
