In which case was the knock-and-announce rule emphasized?

The case that emphasized the knock-and-announce rule is Wilson v. Arkansas. This legal principle requires law enforcement officers to announce their presence and purpose before entering a residence, as a means to respect individuals' rights and to reduce unnecessary violence or property damage.

In Wilson v. Arkansas, the Supreme Court recognized that the knock-and-announce rule is a fundamental aspect of the Fourth Amendment, protecting citizens from unreasonable searches and seizures. The court highlighted the importance of this rule as part of the broader legal framework that safeguards privacy and promotes safe police practices. By reinforcing the necessity of announcing oneself before entering, the ruling helped clarify the limitations placed on law enforcement to ensure they do not overstep boundaries without just cause.

This emphasis on the knock-and-announce rule is essential in understanding constitutional protections during police searches, as it aims to balance law enforcement duties with respect for civil liberties.
