38 L.Ed.2d 427 (1973) (explaining that the reasoning behind this exception is the “need to disarm the suspect in order to take him into custody [and] ... the need to preserve evidence on his person for later use. at trial”). Moreover, as the Supreme Court held in Rawlings v. Kentucky, 448 U.S. 98, 110-11 n. 6, 100 S.Ct. 2556, 65 L.Ed.2d 633 (1980), the search-incident-to-a-lawful-arrest rule also permits an officer to conduct a full search of an arrestee’s person before he is placed under lawful custodial arrest as long as “the formal arrest follow[s] quickly on the heels of the challenged search of ... [his person]” and the fruits of that search are not necessary to sustain probable cause to arrest him. Cf. Knowles v. Iowa, 525 U.S. 113, 116-19, 119 S.Ct. 484, 142 L.Ed.2d 492 (1998) (<HOLDING>); Smith v. Ohio, 494 U.S. 541, 110 S.Ct. 1288,
holding that although the investigation of the traffic offense that served as the basis for the stop was complete when the officer issued the citation the officers continued detention of the appellant thereafter for a canine search was lawful because during the investigation of the traffic offense the officer had developed a reasonable suspicion that the appellant had committed a drugrelated offense holding that the searehincidenttoalawfularrest rule does not apply to a warrantless search that provides the probable cause for the subsequent arrest because one cannot justify the arrest by the search and then simultaneously justify the search by the arrest holding that the searchincidenttoalawfularrest rule does not apply to an officers search of the defendants vehicle where the officer while subsequently arresting the defendant for druglaw violations based upon that search never actually arrested the defendant for the speeding violation which gave the officer the probable cause to arrest the defendant before the search but rather only issued a citation and reasoning that the rules underlying twin rationales of officer safety and evidence preservation were only minimally present and not present at all respectively in the context of a traffic citation holding that the encounter between an officer and the defendant did not rise to the level of a terry stop until the defendant gave the officer his license and the officer informed the defendant that he was going to be given a patdown holding that evidence obtained from a search made subsequent to an illegal stop was admissible when before the search the police officer discovered that there was an outstanding arrest warrant for the defendant and the defendant was thereupon arrested pursuant to that warrant
