There is no de minimus exception to enable a dog sniff after the purpose of a stop has concluded. Extending the stop is unreasonable. State v. Baker, 2010 UT 18, 229 P.3d 650, 651 Utah Adv. Rep. 25 (2010), aff’g State v. Baker, 2008 UT App 115, 182 P.3d 935 (2008):
B. No De Minimis Exception Allows Officers to Conduct a Dog Sniff After the Purpose of the Stop Has Concluded
[*P28] The State also argues that because there was only a short amount of time between the completion of the arrest of the driver and the arrival of the K-9 unit, we should hold that any extension of the detention of the passengers was de minimis. But “even a small intrusion beyond the legitimate scope of an initially lawful search is unlawful under the Fourth Amendment.” Schlosser, 774 P.2d at 1135.
[*P29] Because a trained narcotics-detection dog alerts police only to the presence of contraband, and there is no Fourth Amendment right to possess contraband, the United States Supreme Court has held that a dog sniff is not a search under the Fourth Amendment. United States v. Place, 462 U.S. 696, 707, 103 S. Ct. 2637, 77 L. Ed. 2d 110 (1983). Based on the premise that a dog sniff is not a search, the Supreme Court has also found that a drug-trained dog may walk the perimeter of a lawfully detained vehicle even if police have no reasonable suspicion that the vehicle occupants are engaged in drug-related activity so long as the dog sniff search does not extend the duration of the stop. Illinois v. Caballes, 543 U.S. 405, 408, 125 S. Ct. 834, 160 L. Ed. 2d 842 (2005). However, “[a] seizure … can become unlawful if it is prolonged beyond the time reasonably required to complete that mission.” Id. at 407.
[*P30] Some jurisdictions have held that because police may conduct a dog sniff of the exterior of the vehicle during the course of a lawful traffic stop, they may also detain vehicle occupants for a short amount of time after the purpose of the stop has concluded in order to conduct a dog sniff search. … However, many jurisdictions have recognized that any extension of a stop after officers have completed the purpose of their stop violates the Fourth Amendment. …
. . .
[*P58] Because officers had finished processing the arrest of the driver and were not allowed to conduct a search incident to her arrest, we hold that they had improperly extended the duration of Mr. Baker’s detention at the time the dog sniff occurred. However, we decline to apply the exclusionary rule to the evidence obtained as a result of this violation because the officers acted in good faith reliance on previous precedent that allowed them to conduct a search of the vehicle incident to arrest. But we find that the officers lacked reasonable articulable suspicion that the passengers posed a threat to their safety at the time they conducted the pat-down search of Mr. Baker. Accordingly, we affirm the decision of the court of appeals.

"A system of law that not only makes certain conduct criminal, but also lays down rules for the conduct of the authorities, often becomes complex in its application to individual cases, and will from time to time produce imperfect results, especially if one's attention is confined to the particular case at bar. Some criminals do go free because of the necessity of keeping government and its servants in their place. That is one of the costs of having and enforcing a Bill of Rights. This country is built on the assumption that the cost is worth paying, and that in the long run we are all both freer and safer if the Constitution is strictly enforced." —Williams v. Nix, 700 F. 2d 1164, 1173 (8th Cir. 1983) (Richard Sheppard Arnold, J.), rev'd Nix v. Williams, 467 US. 431 (1984).
"The criminal goes free, if he must, but it is the law that sets him free. Nothing can destroy a government more quickly than its failure to observe its own laws, or worse, its disregard of the charter of its own existence." —Mapp v. Ohio, 367 U.S. 643, 659 (1961).

"There have been powerful hydraulic pressures throughout our history that bear heavily on the Court to water down constitutional guarantees and give the police the upper hand. That hydraulic pressure has probably never been greater than it is today." — Terry v. Ohio, 392 U.S. 1, 39 (1968) (Douglas, J., dissenting).

"It is a fair summary of history to say that the safeguards of liberty have frequently been forged in controversies involving not very nice people. And so, while we are concerned here with a shabby defrauder, we must deal with his case in the context of what are really the great themes expressed by the Fourth Amendment." —United States v.

"The course of true law pertaining to searches and seizures, as enunciated here, has not–to put it mildly–run smooth." —Chapman v. United States, 365 U.S. 610, 618 (1961) (Frankfurter, J., concurring).
"A search is a search, even if it happens to disclose nothing but the bottom of a turntable." —Arizona v. Hicks, 480 U.S. 321, 325 (1987)
"For the Fourth Amendment protects people, not places. What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection. ... But what he seeks to preserve as private, even in an area accessible to the public, may be constitutionally protected." —Katz v. United States, 389 U.S. 347, 351 (1967)
“Experience should teach us to be most on guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” —United States v. Olmstead, 277 U.S. 438, 479 (1925) (Brandeis, J., dissenting)
“Liberty—the freedom from unwarranted intrusion by government—is as easily lost through insistent nibbles by government officials who seek to do their jobs too well as by those whose purpose it is to oppress; the piranha can be as deadly as the shark.” —United States v. $124,570, 873 F.2d 1240, 1246 (9th Cir. 1989)

"In Germany, they first came for the communists, and I didn't speak up because I wasn't a communist. Then they came for the Jews, and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists, and I didn't speak up because I wasn't a trade unionist. Then they came for the Catholics and I didn't speak up because I wasn't a Catholic. Then they came for me–and by that time there was nobody left to speak up."

“Children grow up thinking the adult world is ordered, rational, fit for purpose. It’s crap. Becoming a man is realising that it’s all rotten. Realising how to celebrate that rottenness, that’s freedom.” – John le Carré, The Night Manager (1993), line by Richard Roper
"The point of the Fourth Amendment, which often is not grasped by zealous officers, is not that it denies law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime." —Johnson v. United States, 333 U.S. 10, 13-14 (1948)
