Which factor makes a search reasonable without a warrant in the absence of consent?

• A. Exigent circumstances
• B. The suspect's consent
• C. A crowd's presence
• D. A tip from a neighbor

Answer: (A)

Exigent circumstances allow a warrantless search when waiting to obtain a warrant would put people at risk or allow the imminent destruction of evidence. In such moments, the urgency of the situation makes delaying unreasonable, so a search can be considered reasonable even without a warrant or the suspect’s consent. The key idea is that the action is necessary to address an immediate danger, prevent a pursuit from becoming deadly, or preserve evidence that could be spoiled if police had to wait. A crowd’s presence or a neighbor’s tip alone doesn’t create that urgent need; they may contribute to probable cause or context, but they don’t by themselves justify bypassing a warrant when there’s no consent.
