On the other hand, warrantless search and seizure of properties are not illegal, if the objects being searched are in plain view. Exigent circumstances exist in situations where a situation where people are in imminent danger, where evidence faces imminent destruction, or prior to a suspect's imminent escape.

For instance, a warrantless search may be lawful, if an officer has asked and is given consent to search if the search is incident to a lawful arrest if there is probable cause to search and there is exigent circumstance calling for the warrantless search. In general, most warrantless searches of private premises are prohibited under the Fourth Amendment, unless specific exception applies. However, the Supreme Court has departed from such requirement, issue of exclusion is to be determined solely upon a resolution of the substantive question whether the claimant's Fourth Amendment rights have been violated, which in turn requires that the claimant demonstrates a justifiable expectation of privacy, which was arbitrarily violated by the government. To claim violation of Fourth Amendment as the basis for suppressing a relevant evidence, the court had long required that the claimant must prove that he himself was the victim of an invasion of privacy to have a valid standing to claim protection under the Fourth Amendment. However, the Fourth Amendment does not guarantee protection from all searches and seizures, but only those done by the government and deemed unreasonable under the law. The ultimate goal of this provision is to protect peopleРІР‚в„ўs right to privacy and freedom from unreasonable intrusions by the government.

Constitution provides that 'he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.'
