Re. Anarchists
Thats easy, I had that on 3 1/2" floppy back in the day.
Also a collection of downloaded short stories, any number of random Usenet archives, saved web pages, etc.
Just having the material means nothing without intent.
It is interesting to note that as yet, the very limited situations where the written word is "illegal" are under exceptional circumstances like works of literature dealing with controversial subjects.
It should also be noted that a few years back, it was revealed that the UK Government collected extensive files on folks interested in UFOs, and that information itself was deemed to be classified.
It later emerged that a number of them were actual agents of HM Government investigating said claims as part of their employment. So the agents were in fact observing each other's actions while being unaware that they themselves were being observed. Sound Orwellian yet?
