such a view, are subject to seizure. United States v. Gay, 774 F.2d 368 (10th Cir. 1985). The district court did not err in denying Smith’s Motion to Suppress. When reviewing a denial of a motion to suppress, the appellate court must consider the evidence presented at trial in the light most favorable to the Government. United States v. Rios, 611 F.2d 1335 (10th Cir. 1979).
The “probable cause” justifying a warrantless search is identical with that required to justify issuance of a search warrant. In Illinois v. Gates, 462 U.S. 213, 235, 238-239, 103 S.Ct. 2317, 2330, 2332, 76 L.Ed.2d 527 reh’g. denied, 463 U.S. 237, 104 S.Ct. 33, 77 L.Ed.2d 1453 (1983), the Supreme Court carefully identified the “probable cause” standard to be used in reviewing search warrant applications:
Finely tuned standards such as proof beyond a reasonable doubt or by a preponderance of the evidence, useful in formal trials, have no place in the magistrate’s decision.
[T]he task of the issuing magistrate is simply to make a practical, commonsense decision whether, given all the circumstances set forth in the affidavit before him, ... there is a fair probability that contraband or evidence of a crime will be found in a particular place. And the duty of a reviewing court is simply to ensure that the magistrate had a “substantial basis for ... concluding]” ... that probable cause existed.
In United States v. Lopez, 777 F.2d 543, 551 (10th Cir.1985), we observed:
Probable cause is measured against an objective standard. The facts and circumstances must warrant a prudent man in believing that an offense has been or will be committed.
United States v. Salinas-Calderon, 728 F.2d 1298 (10th Cir. 1984). More specifically, probable cause must be evaluated in relation to the circumstances as they would have appeared to a prudent, cautious and trained police officer.
United States v. McCormick, 468 F.2d 68, 73 (10th Cir.1972),
cert. denied, 410 U.S. 927, 93 S.Ct. 1361, 35 L.Ed.2d 588 (1973).
Even if probable cause exists to conduct a warrantless search, such as here, still such a search is unlawful as violative of the Fourth Amendment1 unless justified by consent to search, search incident to arrest, or exigent circumstances. United States v. Jacobsen, 466 U.S. 109, 104 S.Ct. 1652, 80 L.Ed.2d 85 (1984); Arkansas v. Sanders, 442 U.S. 753, 99 S.Ct. 2586, 61 L.Ed.2d 235 (1979); Mincey v. Arizona, 437 U.S. 385, 98 S.Ct. 2408, 57 L.Ed.2d 290 (1978); Schneckloth v. Bustamonte, 412 U.S. 218, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973); United States v. Espinosa, 782 F.2d 888 (10th Cir.1986); United States v. Gay, supra; United States v. Tabor, 722 F.2d 596 (10th Cir.1983).
The basic aspects of the “exigent circumstances” exception are that (1) the law enforcement officers must have reasonable grounds to believe that there is immediate need to protect their lives or others or their property or that of others, (2) the search must not be motivated by an intent to arrest and seize evidence, and (3) there must be some reasonable basis, approaching probable cause, to associate an emergency with the area or place to be searched.
In Arkansas v. Sanders, 442 U.S. 753, 99 S.Ct. 2586, the Supreme Court discussed the Fourth Amendment and exceptions to its warrant requirements:
These [exceptions to the warrant requirement] have been established where it was concluded that the public interest required some flexibility in the applica
