That case shows the real next stage in 'Political Correctness gone mad' - for those who haven't seen it, it's about a pair of students who were reported for having a copy of the 'Al Quaida Training Manual' on a PC. It was relevant to the course they were taking (although not a set book). It was also available free from the US Department of Justice website and you could buy it on Amazon.
Yet still they were reported for having it, the University called the Police, they were arrested and held for a while uncharged and interrogated, homes searched etc etc.
And now one of them faces deportation for some very minor errors on his immigration papers. Sounds like 'look, we found *something* at least' to me.
I'm sure there are people out there who need deeper investigation and swift, decisive action taking against them. Doesn't sound like this is one of them to me.
