The fourth circuit court of appeals decides United states v. Moylan:

       We recognize … the undisputed power of the jury to acquit, even if its verdict is contrary to the law as given by the judge, and contrary to the evidence.  This is a power that must exist as long as we adhere to the general verdict in criminal cases, for the courts cannot search the minds of the jurors to find the basis upon which they judge.  If the jury feels the law is unjust, we recognize the undisputed power of the jury to acquit, even if its verdict is contrary to the law as given by a judge, and contrary to the evidence. … If the jury feels that the law under which the defendant is accused is unjust, or that exigent circumstances justified the actions of the accused, or for any reason which appeals to their logic or passion, the jury has the power to acquit, and the courts must abide by that decision. (emphasis added)
