Steve Wedemeyer noticed jurors rolling their eyes and sighing during a $5 million breach of contract case in Houston—at the end of which he won a take-nothing verdict for his defense client.

Wedemeyer spotted the jurors’ gestures while opposing counsel presented the plaintiff client’s witnesses and evidence. He thought this body language showed that they were skeptical about the plaintiff’s case and that they’d grown tired during the two-and-a-half-week proceeding. So he decided that his client, an insurance company, should quit while it was ahead; he would not call any witnesses but instead go straight to closing arguments.
