Follow that link and read this story.  It is disconcerting.  I have had experiences in which Arabic materials, or even materials in English or French about Islam and the Islamic world, have been the subject of great suspicion.  Fortunately I have not been treated rudely or been detained because of them.  It does worry me, though.
