Criminal Law Basics

Concurrence is not an element of a crime, but rather a requirement for criminal liability. It refers to the simultaneous occurrence of actus reus and mens rea.

Actus reus is the voluntary and intentional commission of an act that is prohibited by law. It is one of the two essential elements of a crime, along with mens rea.

Mens rea is the mental state of a person who commits a crime. It refers to the intent, knowledge, or recklessness with which the actus reus is committed.

Negligence is not a type of mens rea, but rather a lesser degree of culpability that may be sufficient for civil liability, but not necessarily for criminal liability.

The insanity defense is a defense that claims that the defendant was not criminally responsible for their actions due to a mental disorder that prevented them from understanding the wrongfulness of their conduct.

The entrapment defense is a defense that claims that the defendant was coerced or tricked into committing a crime by law enforcement officials.

Self-defense is a defense that claims that the defendant used force to protect themselves or others from imminent harm.

The criminal justice process is the process by which a person accused of a crime is brought to trial and, if convicted, punished.

The first step in the criminal justice process is the arrest of the suspect.

The purpose of a preliminary hearing is to determine if there is probable cause to believe that the defendant committed the crime.

Trial by jury is the trial in which a jury decides whether the defendant is guilty or not guilty of the crime.

An appeal is the process by which a defendant can challenge the conviction or sentence in a criminal case.

The Supreme Court of the United States is the highest court in the United States.

Legislation is the process by which a law is created or changed.

Adjudication is the process by which a court decides a case and creates a law that is binding on future cases.
