What are the key principles and procedures of criminal law, and how do they ensure fairness, justice, and due process in legal proceedings?

Criminal law encompasses statutes, regulations, and legal principles that define and punish offenses against society, such as murder, theft, assault, and fraud. It establishes procedures for investigating crimes, prosecuting offenders, and adjudicating guilt or innocence in court. Key principles include presumption of innocence, burden of proof, right to a fair trial, legal representation, and proportionate sentencing. Criminal law seeks to protect individual rights, maintain public order, and deter criminal behavior through enforcement and rehabilitation measures.
