The main purpose of criminal law is to maintain public order, deter criminal behavior, and punish individuals who break the law while protecting the rights of individuals in society.

The exclusionary rule prevents evidence obtained through illegal searches or seizures from being used in court against a defendant.

The Miranda warning is a legal warning given to individuals who are in custody and about to be interrogated. It ensures the individual's Fifth Amendment rights are protected, including the right to remain silent and the right to an attorney.

The right to a speedy trial, guaranteed by the Sixth Amendment, ensures that an accused person is tried within a reasonable time, preventing prolonged detention without trial.

Double jeopardy, protected by the Fifth Amendment, prevents an individual from being tried twice for the same offense once acquitted or convicted.

A felony is a more serious crime, typically punishable by imprisonment for over one year or death, while a misdemeanor is a lesser offense punishable by less than a year in prison or a fine.

Bail is set to ensure that an accused individual returns for their trial. It allows the accused to remain free until their trial while guaranteeing their presence in court.

The Fourth Amendment protects individuals from unreasonable searches and seizures by the government and requires warrants based on probable cause for searches or arrests.

Probable cause is the standard of evidence required for law enforcement to make an arrest, conduct a search, or obtain a warrant. It ensures that actions are based on reasonable grounds to suspect criminal activity.
