An individual has quite a few rights when in court. One right is that everyone is entitled to a lawyer and a fair trial as seen in "Gideon's Trumpet" when Gideon gets convicted of robbing money from the pool house he soon goes to trial after that. At first, he cannot afford to pay for a lawyer so he defends himself. A person in court can also choose to defend themselves in court if they feel that they do not need a lawyer to defend them.
Another right an individual has while in court is to be appointed to a local lawyer that can represent them in court. If you cannot afford a lawyer and also do not want to represent yourself then you can represent yourself. In court, the responsibility of an individual is to behave properly and not to yell or scream at the judge. If someone is brought up to the witness stand, then their responsibility is to tell the truth and not lie.
Showing up to court especially if you " re the judge, part of the jury, or the defendant /complaint if is definately the responsibility of those individuals. Not fulfilling responsibilities in court can affect whether or not a person is able to be proven innocent. If an individual does not fulfill his or her responsibility even if it wasn't intentional then there's a good chance that they can be penalized to being guilty even if they weren't guilty. For example, if a lawyer dosen't have evidence at court then they messed up pretty bad in their responsibility to defend their client in court because most likely they will not win the case without evidence. In this case the lawyer would probably be fired since there was no point for him / her if they were going to mess up so badly. The ultimate value of the American legal system presented is that everyone is entitled to a fair trial and to be represented by a lawyer.
This is truly the ultimate value because without this right then a lot of people would not have been able to be proven innocent. Not everyone can afford a lawyer or afford to have a trial but with this right they are guaranteed to having those two things. These movies do effectively communicate this value in both movies. The boy in "Twelve Angry Men" was able to have a trial to see if he did in fact kill his father or not.
He was entitled to a trial therefore, he was able to be proven innocent. In "Gideon's Trumpet", Gideon was able to have a trial twice but a lawyer once. Like the boy in "Twelve Angry Men", Gideon also proved that he was innocent. Of course not everyone that is entitled to a trial is proven innocent but if someone is convicted then they have the opportunity to prove that they indeed are innocent.
