It's so awesome how moderators allow for a free and open discussion on HN
Given that there was a large Assange thread yesterday (https://news.ycombinator.com/item?id=22351183), and a large thread on the Assange/torture question a few weeks ago (https://news.ycombinator.com/item?id=22201381), I don't think this letter contains significant-enough new information to support a solid HN discussion. This topic is divisive enough as it is, and in the absence of significant new information, threads tend to degrade even faster than usual.
