(I posted some excerpts, before, then deleted them....I'm sure this is being paranoid, as the Canadian press is displaying the link prominently. But on further reflection I'd just as soon not excerpt an article for which a reporter may be jailed, at least not without the express written consent of major league baseball, a.k.a. Moe and von.)
I see why she was the one targetted. It goes into much more detail than any other source I've seen about the charges against Arar, including some that were new to me. Here is a link to a NY Times article on Tabligh Jamaat, the Muslim missionary group to which the leaked documents tied Arar.
It's quite an article. I'm embarrassed for having missed it. It gives a better understanding of the basis on which Arar and Almalki were suspected. But it also gives still more evidence of collaboration between Canadian and U.S. intelligence and Arar's interrogators/torturers. Read the whole thing, and make of it what you will.
