But (Score 1)

Surely the people who DB should be sueing are those that host the content, rather than those which point at it? - But then we all know how it is with caching these days? The content could probably be pulled yet the mirros/ caches would be lting around for a while.

As for it being quick, well DB suffered a lot of bad press from a 'couple' (definately one really bad accident that I remember) of accidents and they are the target for green activists on a yearly basis so ... I expect from a corporate view they have to be seen to be protecting their customers. A court case is probably far cheaper than upgrading the carriages on the railway.
