:::Some people are deleting the links to the pdf files of the magazine, without seeking consensus. I think this is WP:CENSOR, and the files should go back in. They've given many reasons  first, because it shows how to construct a bomb that can kill people, second, because it's supposedly a "linkfarm," and now because it's supposedly a copyright violation. I don't think it's a copyright violation, and I think this is a pretext for deleting information you don't agree with. This is clearly the purpose of an external link, to link to further information of direct relevance to the article, which this certainly is. I think it's important for people to be able to read this magazine, and make up their own minds, rather than getting second-hand accounts. If the terrorists are so dangerous, then we ought to know as much about them as we can to get insight into their thinking. We should read this for all the reasons given by John Stuart Mill in On Liberty. Unless someone can give a convincing reason here in talk, I think the links should go back in.
