A lot of courts do things differently. In Colorado the jury has the right to recess at 5 or 6 and ask to reconvene on the following business day. I'm not sure how it works in Florida but id imagine its somewhat similar. If I'm the defense I'm hoping the jury comes to a verdict tonight and being that they're sequestered I'd be willing to bet the jurors want to wrap it up tonight so they don't spend the entire weekend locked in a hotel room with only supervised family visitation and no access to television or social media.
If acquittal is decided, who is going to provide the personal protection for the six folks on the jury who came up with that decision. I feel that they might really be considering their safety when making their decision.
