A true emergency can excuse the warrant requirement, because the Fourth Amendment is concerned with reasonableness and there are situations where waiting for a warrant would be unreasonable. But the exigent-circumstances exception is narrow, and it is one the State has to prove with specific facts. The recurring fight is whether there was a real emergency or a label applied after the fact to justify a search the officers wanted to do anyway.
Exigency is measured by the facts the officer knew at the time. A real, immediate emergency can excuse the warrant; a vague or police-created one cannot.
Is this a DUI blood draw? The most common exigency fight is over a warrantless blood draw in a DUI case. See Exigent Circumstances and the DUI Blood Draw.
A True Emergency
The exception covers a short list of genuine emergencies, including hot pursuit of a fleeing suspect, the imminent destruction of evidence, and the need to render aid or prevent harm. In each, the common thread is that there is no time to get a warrant. The State has to identify which exigency applied and point to the specific facts that established it at the moment the officer acted, not a general sense that moving quickly was convenient. Florida’s seminal home-entry case is Benefield v. State, 160 So. 2d 706 (Fla. 1964), and Murphy v. State, 898 So. 2d 1031 (Fla. 5th DCA 2005), requires an objectively reasonable belief that evidence would be destroyed before a warrant could be obtained.
The Police Cannot Manufacture It
An emergency the police created does not count. In Kentucky v. King, 563 U.S. 452 (2011), the U.S. Supreme Court held that officers may rely on an exigency only if they did not create it by engaging in or threatening conduct that violates the Fourth Amendment. When the urgency is the product of the officers’ own choices, such as announcing their presence in a way designed to provoke the destruction of evidence, the exception does not apply. Florida courts scrutinize police-created exigencies closely, as in Hanifan v. State, 177 So. 3d 277 (Fla. 2d DCA 2015).
Exigency Is Narrow and Specific
Courts resist broad emergency exceptions. In Mincey v. Arizona, 437 U.S. 385 (1978), the U.S. Supreme Court refused to recognize a general exception for the scene of a homicide, holding that even there a warrant or a specific exigency is required. And in the DUI setting, Missouri v. McNeely, 569 U.S. 141 (2013), held that the natural dissipation of alcohol does not create a per se emergency justifying a warrantless blood draw in every case. The question is always whether a real, immediate emergency existed on the particular facts.
Common Claimed Exigencies
The recognized categories are narrow. Hot pursuit of a fleeing suspect, the imminent destruction of evidence, and the need to render emergency aid or prevent harm are the usual ones. The problem is how often these labels are attached after the fact to conduct that did not really fit. Officers describe a fear that evidence would be destroyed without showing any concrete basis for it, or claim an emergency that the body camera does not support. Because the exception swallows the warrant requirement when it applies, courts scrutinize whether the emergency was real, immediate, and beyond the time it would have taken to get a warrant.
How We Test the Emergency
The questions are concrete. What exactly was the emergency, and what facts known to the officer at the time established it. Could a warrant have been obtained in the time available, including by phone or electronic means. Did the police create the urgency themselves through their own conduct. And did the scope of the entry or search match the emergency, or did it expand into a general search once the officers were inside. The timeline, the recordings, and the dispatch records usually show whether there was a true exigency or an after-the-fact justification, and a manufactured or overstated emergency is a basis for suppression.
Exigency is the exception officers reach for when they had time to get a warrant and did not, so I look closely at whether the emergency was real. As a former public defender, I test the timeline and the officers’ own conduct against Kentucky v. King, because an emergency the police manufactured is not the kind that excuses a warrant. When the claimed urgency does not hold up, I move to suppress the fruits of the entry.

Questions About Exigent Circumstances
What are exigent circumstances?
They are emergencies that make it impractical to get a warrant, such as hot pursuit of a fleeing suspect, the imminent destruction of evidence, or the need to give emergency aid. When a true exigency exists, officers may act without a warrant, but only as far as the emergency requires.
Who has to prove the emergency?
The State. Because a warrantless entry or search is presumptively unreasonable, the government has to prove that a genuine exigency existed at the time, based on the facts the officer knew at the time.
Can police create an emergency and then use it?
No. In Kentucky v. King, the Supreme Court held that officers cannot rely on an exigency they created by violating or threatening to violate the Fourth Amendment. A police-manufactured emergency does not justify a warrantless search.
Is there a general crime-scene exception?
No. In Mincey v. Arizona, the Supreme Court rejected a blanket exception for the scene of a serious crime. Even at a homicide scene, officers need a warrant or a specific recognized exception to search.
Does this apply to DUI blood draws?
It can, but it is not automatic. In Missouri v. McNeely, the Supreme Court held that the natural dissipation of alcohol in the blood does not by itself create an exigency in every DUI case. Whether an emergency justified a warrantless draw is decided case by case.
How do you challenge an exigency claim?
By testing whether the emergency was real and immediate, whether a warrant could have been obtained in time, whether the police created the situation, and whether the search stayed within the scope of the emergency. The recordings and timeline often tell the story.
