Beds starts off this unpub'd decision here, like this:
Writers in training are often told to “show, don’t tell” – allow the reader to experience the story through action rather than being spoon-fed it in narrative. “Show, don’t tell” is also good advice for lawyers. Indeed, “show, don’t tell” is a defining skill in trial advocacy and especially important in plaintiff’s civil litigation. A plaintiff cannot merely say he has a claim; he must actually prove it. He must “show” his evidence, rather than “tell” through his allegations.
