One good look at the memos, which were all over the TV screen, would show that they were proportionally spaced and that the font was either Times New Roman or Palatino. Anyone who has used Microsoft Word more than once or twice -- an attorney who types his own documents, for example -- might be familiar with what lies behind that pull-down menu labeled "Format."
And I suspect that Buckhead might have been using an arcane, high-tech, state of the art device known as a "VCR," which allowed him to record the broadcast and review it over and over to spot these characteristics.
Imagine that.
