Search and Seizure
Collective knowledge doctrine
In determining whether an officer had probable cause for a warrantless search of a vehicle, information known to the DEA, which requested the stop, can be imputed to him under the collective knowledge doctrine.
“Other appeals courts similarly have concluded that the application of the collective knowledge doctrine is unaffected by an officer’s use of a cover story to disguise a stop as a mere traffic stop. See United States v. Chavez, 534 F.3d 1338, 1341-42 (10th Cir. 2008) (where officer stopped suspect at DEA’s request, the fact that the officer pretended that the stop was for a failure to turn on headlights in order to conceal a confidential informant’s identity and protect the integrity of the DEA investigation did not preclude the application of the collective knowledge doctrine); United States v. Ramirez, 473 F.3d 1026, 1038 (9th Cir. 2007) (Kozinski, J., concurring) (‘disguising the stop as a “traffic Stop” was a valid law enforcement tactic calculated to ensure an officer’s safety . . . [and] did not change the nature of the stop,’ or the fact that the stop was made at the direction of an officer who had probable cause, such that the collective knowledge doctrine applies). Moreover, the Fifth and Tenth Circuits have considered instructions like the one Gutierrez gave Simon, and concluded that such an instruction does not bar the application of the collective knowledge doctrine.”
