I was extremely impressed by Orin's post on the domestic surveillance issue -- and also by the general quality of the comments, which are mostly very substantive, thoughtful, and well-informed. Don't be distracted by the first comment, which is from a commenter whose comments often tend toward sarcasm and political point-scoring. Read past it and past the thank-you notes to Orin (which are much appreciated but which I can't claim are deeply substantive), and you'll see a generally excellent discussion.
