Which scenario would likely not require a search warrant?

Searching with consent is a scenario that typically does not require a search warrant because the individual has voluntarily agreed to allow law enforcement to conduct the search. Legally, when a person provides consent, they are relinquishing their expectation of privacy in that specific context, thus negating the need for a warrant. Consent must be given freely and voluntarily, and it can be withdrawn at any time during the search.

In contrast, conducting a search in a person's home generally requires a warrant due to the heightened expectation of privacy individuals have in their residences. Searching a public place often does not need a warrant because these areas are accessible to the general public, thus lowering the expectation of privacy. Searching for evidence of a crime with probable cause usually mandates a warrant as well, since authorities must demonstrate that there is a significant reason to believe a search would yield evidence of a crime. Therefore, consent is a valid exception to the warrant requirement.
