Criminal Law is the body of rules and statutes that defines conduct prohibited by the government because it threatens and harms public safety and welfare and that establishes punishment to be imposed for the commission of such acts. Punishment is allowed because crimes must generally be committed with malicious intent. A criminal case differs from a civil one because the criminal is sued by the state while in a civil case, the victim of the crime brings the suit. To be convicted, the criminal must be shown to have concurrently completed the prohibited act, or actus reus, with the culpable mental state, or mens rea. This will be true unless the conduct resulted in a strict liability crime, for which only the prohibited act must be shown to convict the criminal.
States have primary and inherent authority to pass laws prohibiting or punishing any acts, as long as such laws do not contradict the federal or state constitutions. Thus, laws will differ between the states. Many states have chosen to update their laws in accordance with the Model Penal Code. The federal government has limited jurisdiction to prohibit or punish conduct.
