I want to know about the jury system in the USA. Do they decise that a person is guilty or innocent in all cases of crime? Would you let me know something abut 'Jury"? Thank you.

Probably most, but I wouldn't say "all."

For example, a person can choose to have a "bench trial" in which there is no jury; the person has chosen the judge to act in place of the jury.

Of course! I'd be happy to explain the jury system in the USA to you.

In the United States, the jury plays a crucial role in the criminal justice system. When someone is accused of a crime, a trial takes place to determine their guilt or innocence. In most criminal trials, a panel of ordinary citizens called the jury is selected to hear the evidence, assess the credibility of witnesses, and ultimately decide whether the accused is guilty or innocent.

The jury's role is to impartially evaluate the facts presented during the trial, under the guidance of the judge. They are responsible for determining the guilt or innocence of the defendant based on the evidence and the application of the law as instructed by the judge. Their decision must be reached unanimously, except in some specific cases where a majority verdict is permitted.

However, it's important to note that not all cases involve a jury trial. In some instances, such as minor offenses or certain specialized courts, a judge may render a verdict without a jury. In other cases, the accused may also choose to waive their right to a jury trial and have a judge decide the outcome.

To participate in a jury, individuals are randomly selected from a pool of potential jurors, often from voter registration or driver's license databases. The selection process is designed to ensure diverse representation and to provide fair and impartial decision-making. Potential jurors are then questioned by the attorneys and the judge to determine if they can make an unbiased decision based solely on the evidence presented.

So, to answer your question, in the USA, the jury does indeed decide whether a person is guilty or innocent in most criminal cases. The jury system is a fundamental component of the American legal system, prioritizing the involvement of ordinary citizens in the pursuit of justice.
