According to this story, the jury was not present when Judge Nelson asked Zimmerman if he planned to testify. He replied that he needed until "the end of the day" to decide, while overruling Don West's objections to her questions. She then agreed to give Z more time, while maintaining that the court has the right to know if Z will testify.

It's not possible to tell from the videos whether the jury is present or not, unless they happen to mention the fact one way or the other.
Now that’s what I’m talking about. Thanks!
