The PDF report is not clear on exactly how a representative sample was
chosen (from what? by what method? from what superset?). Until that is
clear, the report is suspect on methodological grounds, the more so
given the strong interest AK Zensur has in the findings.

However, one thing it implies is: If the list is not made available,
research and analysis such as this cannot be performed except by the
holder of the list. In other words, there is no way for independent
evaluation of the success or failure of the program. That's something to
think about in the Australian context, where the Government has
repeatedly said it will keep the list secret.

Regards, K.
