Orin Kerr has this strong analysis, explaining the importance of today's Second Circuit decision upholding the convictions of several individuals involved in bombing American embassies in Africa ten years ago. (The decision is available here, split into 4th and 5th Amendment issues and other claims, as well as here). Here is Andy McCarthy, one of the federal prosecutors who worked on the case.
As Kerr's discussion makes clear, there is some impact on a small number of our terrorism investigations here. The major impact, of course, is that the embassy bombers will remain behind bars.
