In California criminal cases, the state prosecutes individuals accused of crimes. The legal process includes investigation, charging, arraignment, trial, and sentencing. Expert witnesses are vital in these cases. They have specialized knowledge and skills that help explain complex issues to the court.
Expert witness insights can significantly affect the trial’s outcome by making technical details clear and understandable for the jury and judge, which can influence the final verdict.

These professionals can challenge the prosecution’s evidence or support the defense’s claims. Their testimony can introduce reasonable doubt, which is essential for acquittal. By breaking down complicated information into understandable terms, expert witnesses help the jury make informed decisions.
