Here's a question on a slightly related note. It is widely known that Gottfrid Svartholm (anakata) is not provided access to books as opposed to Peter Sunde. But, Gottfrid is allowed to receive letters. I was wondering if there is any legal restriction on the content of the letters sent to such prisoners. If not, would it be OK if books are sent by the page via letters either as-is or paraphrased?
