The equipment they owned was confiscated. That really was the sum of the punishment. Why mice and keyboards and such were taken by the police is beyond me.
On the scale of Icelandic justice this was a pretty harsh judgement. You get smaller fines for aggravated assaults round here.
Also, like I said before the major defeat for 21. century computing was that "making available" was made punishable. The law says otherwise, but in the future weak willed judges in Iceland are going to look back on this ruling for support.
