I just [inexplicably] watched that episode. 20 minutes of my life that I'll never get back. But, anyway, the points that Kurtz and Zell were making were intentionally different and the judge didn't understand the technology enough to appreciate the difference.
Basically, you have:
thinkpad_disk -> software_magic -> human_readable_info
Now, Kurtz was arguing that it was actually:
thinkpad_disk -> state's_software_magic -> state's_human_readable_info
and
\
thinkpad_disk -> defense's_software_magic -> defense's_human_readable_info
And that state's_human_readable_info and defense's_human_readable_info were different and that he hadn't had an opportunity to see states's_human_readable_info and therefore he didn't know how to cross examine the witness on it. So he wanted that witness's testimony and anything related to thinkpad_disk thrown out.
When he lost that battle, he switched to asking for them to at least give him either state's_software_magic or state's_human_readable_info now.
Zell's argument was, we gave them thinkpad_disk so they can get any info that they like from it. We can't give them state's_software_magic because it is top-secret and could have national security implications.
Zell did a good job of kind of muddying the waters so as to not really have to answer the question: if they can't give them state's_software_magic , why can't they at least give them the output of that magic, which is state's_human_readable_info.
