How are the rights of the accused protected and limited by the fourth and fifth amendment?

their purpose is meant to ensure that people are treated fairly if suspected or arrested for crimes. The Fourth Amendment protects people from unreasonable searches and seizures without a warrant. The Fifth Amendment protects individuals from being forced to incriminate themselves. Incriminating oneself is defined as exposing oneself (or another person) to "an accusation or charge of crime," or as involving oneself (or another person) "in a criminal prosecution or the danger thereof."
