You have to dig a little bit when you get to the Kennedy School of Gov't site, but it's worth the effort to read the paper before going to Dershowitz' response.
I'm a little past halfway through the paper and there are some persuasive points in it. I also don't see any antisemitism in the paper, unless one views any criticism of Israel as antisemitism, which some, like Dershowitz, do.
I'm looking forward to finishing and going to read Dershowitz' response. This is an important discussion, and it's worth our time to read both closely.
I don't understand why we shouldn't also question Dershowitz' motivation, though, as well as that of the original researchers.
