What worries me is the term: 'intended to be useful to terrorists'; this is so broad a definition, in theory anything could be deemed as useful to terrorist. For example, how to fly a plane, how to drive a car, self defense techniques.
It also concerns me what implications to freedoms this may have on non-violent polictical protest sites i.e. any site that may critise a governments policy.
I am a UK citizen and am becoming increasingly worried as my freedoms are being slowly litigated for my 'own good' to combat terrorism.
Reminds me of a joke on Red Dwarf: 'Report your friends, family and neighbours... wonderful prizes to be won.'
