Black Screen with White Font as Probable Cause

The EFF has a great example of how people fear what they don't understand. This one is amazing. How many of us have ever used an operating system that was "a black screen with white font which he uses prompt commands on" before?

EVERYONE. All of the popular PC operating systems have this functionality. How do they know he didn't just have a command prompt up in windows maximized to full screen? I just don't understand how this type of insanity continues to be perpetrated within the court system. Blatantly invalid technical details seemingly run rampant.

I think any law activity (warrants, trials, etc.) that includes anything with this much technical detail should be reviewed by someone with at least a slight inkling of what the jargon means. This abuse would have been caught almost immediately if the officer or judge had any training as to what they were attempting to do in this arena.
