    ... when if the range of the features of the training set is severely limited when compared to the range of the features to be detected when the system is applied to live data?

      That will generate a dataset you need for testing, perhaps pulling several dozen years' news stories from around the world, for example.

      But if it somehow simply can't be done - if it's not possible to use the technology without removing our rights, then it is the wrong tool to use. Scrap it.

      Technology does not get to decide what rights we have. Period.

        ... to generate sufficiently realistic test data is exactly the same of that of training a classifier without actually reading the communications used to train said classifier.

        You can't use the classifier you are building to generate the training set.

        And you can't build a test generator without training it with real data, either.  The patterns being sought are too statistically subtle to generate in your test set without the use of real world data.
