Which Constitutional amendment relates to unlawful search and seizure?

The Fourth Amendment of the U.S. Constitution is specifically designed to protect citizens from unreasonable searches and seizures by the government. This amendment ensures that law enforcement officials must have probable cause and, in most cases, a warrant issued by a judge before searching an individual's property or seizing their belongings. The importance of this amendment lies in its role in upholding individuals' rights to privacy and security against arbitrary governmental intrusions.

In a broader context, the Fourth Amendment has significant implications for law enforcement, including the requirement of adhering to proper legal procedures during searches and the consequences of failing to do so, such as the exclusionary rule, which prevents illegally obtained evidence from being used in court. This foundational principle is crucial for maintaining the balance between law enforcement’s duties and protecting individual freedoms.
