Yes. The lawyer was walking on air when he got back to the office to tell about it. If I may digress into a personal story, somewhat pre-Unix. (I was nine years old.) I remember my father showing exactly the same excitement when he returned from testifying as an expert witness for the plaintiff in a near-electrocution case that left the victim paralyzed. A visitor touring a substation had pointed to something to ask what it was, and got hit with a 33,000-volt arc. The defense lawyer tried to discredit the expert, a professor who formerly had been an electrical engineer for a utility company. Lawyer: Have you ever designed a 33,000-volt indoor substation? Prof: I have. Lawyer, changing tactics after an unexpected answer: Do you recognize this book? Prof: I do. Some discussion describing the book, an inventory of utility facilities, for the benefit of the jury. Lawyer, with a hint of triumph: The inventory shows that your former employer has no such substation. Prof: Yes, after a few years we decided it was too dangerous and decommissioned it. ... Lawyer, showing a photo of the busbar that arced: Wouldn't someone have to stretch unusually high to get near to it? Prof: No. That picture was taken exactly [some measurement like 2'3"] from the floor. Lawyer: Do you mean to tell me you know where the picture was taken from, without having been present when it was taken? Prof, pointing to a blown-up engineering drawing on the courtroom wall: This horizontal pipe is seen end-on in the photo. It is dimensioned as being 2'3" from the floor. The plaintiff won.
