  •  Just posted an analysis (4.00)
    I've just finished writing up a layman's analysis of how the NSA surveillance programme likely works.

    I think it makes a fairly decent complement to this fine legal analysis. It would be nice to think about combining and synthesising these and other relevant diaries into a dKosopedia entry or something....

    •  Interesting analysis (none)
      only problem is that Bin Laden and his friends generally don't speak English so it would be foolish for NSA to be searching for terrorist related words in English.

      Arabic has about 8 different dialects (I would think Bin Laden speaks the Saudi dialect), plus throw in Dari, Urdu, Pashtu (languages of Afghanistan and Pakistan), and Persian-Farsi (Iran). I'm sure there are other tribal languages they have to keep track of - Cushitic, Kirundi, Kurdish, Turkomen etc.  I'm not trying to be a smartass - just trying to point out that most of the world does not communicate in English, so how do you set up computer searches?

      As a matter of fact that would be a good indicator of NSA crossing the line - a kind of litmus test. If they are monitering American English communications without a warrant, they are wrong

      •  Text consists of patterns (none)
        It's not significantly difficult to use a computer to identify a language from a small sample of text. I've done this using simple modules written in the Perl programming language. My job at the time was to cull out anything but English, but it's not any more difficult to watch for any of a few dozen languages and dialects and run different key words analyses on those.

        That said, I think they would definitely watch English language traffic as well, expressly because there are so many languages spoken in the Muslim world. The lingua franca in cases where people of many nations need to communicate is often English. In Muslim countries it would more likely be Arabic, though....

        But you're right in your implicit assumption that it is not the NSA's job to try to catch domestic terrorists (i.e. those speaking vernacular US English). That task resides firmly with the FBI.

        •  Correction (none)
          It's closer to about 30 different dialects of Arabic, not just 8.  
          •  One would need (none)
            to toss all the major European languages into the mix as well. Esp. french.

            I don't really see this as a big problem anyhow. It's all 1's and 0's to the hardware and what are American ctizens paying all those nerds at the NSA for anyway if not to capture, decrypt and translate foreign language communications?
