    Once a vehicle is stopped, he explained, [Operation] Valkyrie officers look for indicators of drug trafficking. These indicators are numerous—indeed there is a list of twenty-eight factors in the Operation Valkyrie training manual—and include such things as too little or too much luggage for the stated length of trip, maps from drug source cities or states, and air freshener. Officers are also trained to look for verbal and non-verbal signs of stress and deception, such as nervousness and an overly friendly demeanor. [Operation Valkyrie coordinator] Snyders testified that when Valkyrie officers observe these indicators, they are trained to request consent to search the vehicle. In 1992, Valkyrie officers requested permission to search in approximately fourteen percent of motorist stops, and when requested, over ninety-eight percent of motorists granted consent.

  7.  Florida’s law contains a few scattered provisions giving guidance regarding warrantless searches, e.g. Fla. Stat. § 901.151 (governing stop and frisk); id. § 901.21 (regarding strip searches), but many are explicit or implicit codifications of Supreme Court precedent, e.g., id. § 901.21 (regarding search of arrestees); id. § 933.19 (regarding vehicle searches). In California, Governor Jerry Brown signed into law the California Electronic Communications Privacy Act, S.B. 178, which creates a warrant requirement for digital searches. Otherwise, the state laws remain largely devoid of guidance or restraint, with few exceptions such as the constitutionally required suppression of evidence obtained unreasonably without a warrant, Cal. Penal Code § 1538.5, and a prohibition against warrantless “physical body cavity search[es]” for infraction or misdemeanor arrestees. Cal. Penal Code § 4030(h).
