Yes, a jury decides if a person is guilty or not guilty.
Jury Foreman (or Forewoman)
A person who hears summary jury trials is called an ombudsman.
In order for a person to be charged with a serious federal crime, a federal grand jury must be convened and an indictment issued. The Grand Jury and right to a trial by jury were put in place to make sure citizens weren't victimized by overly eager police officers and prosecutors.
Jury instructions are presented by the judge to the jury. The judge explains what the laws are that govern the case at hand. Jury instructions define the elements of the charged offense and define the burden of proof. Each attorney gives the judge a set of proposed jury instructions. The judge considers each instruction and then decides which ones properly state the law that applies to the case. She then makes her instruction to the jury. The jurors must accept and follow the law as instructed by the judge and use that instruction in their deliberations as they weigh testimony and evidence presented at the trial. Jury instructions are not evidence.
Whatever the jury considers reasonable for a person of ordinary care (in the jurisdiction) to have done (or not done) under similar circumstances. If everyone here'bouts knows something oughta be done, then it's the reasonable person standard, even if nobody elsewheres would do it that way.
