Correct. Jury trials in the US need unanimity from the 12 jurors to either establish guilt or innocence. Anything other than unanimity is a hung jury. Source: I’ve been a member of two juries that went to trial and reached unanimity. Also, be aware that a single juror holding out against the other jurors will go through intense pressure to adopt the prevailing opinion. The other jurors will be pissed that that one person is prolonging the process by days, especially when the judge keeps sending them back to keep deliberating and hopefully reach a unanimous decision. Jury nullification should not be taken lightly as it’s not a walk in the park.
