Defendant Ernesto Ayon was the target of an investigation spearheaded by Officer Scott Williams of the San Jose Police Department’s Metro Unit.  The Metro Unit specializes in narcotics investigations.  On June 19, 2018, at about 9:00 p.m., Officer Williams (in plain clothes) and other officers were following defendant as he drove down West Taylor Street in San Jose.  The officers were watching for a traffic violation that would justify a “pretextual traffic stop.”  It didn’t take long.  As defendant approached the intersection of North San Pedro Street and prepared to make a right turn, he drove into the right-hand-side bicycle lane too early, traveling in the bike lane for about 50 to 70 feet before the start of the broken painted lane line that marks the point where it is legal to move over the line and closer to the curb.  And then he failed to use his turn signal until he actually reached the corner.  Both are violations of the Vehicle Code, albeit relatively minor ones.  As a result, a patrol unit effected a traffic stop within the next couple of blocks.  Body cameras from several of the officers at the scene recorded the events that followed, marking the exact time of each step of the contact, and described in excruciating detail by the Appellate Court.  But as is relevant to the issues here, it was noted that defendant’s documentation (license and registration) were obtained by the first officer to contact him.  As a warrant check was being run, defendant was approached by Officer Williams (who before contacting him had “donned a department-approved uniform.”) and another officer at about three and a half minutes into the contact.  Defendant was asked Officer Williams to step out of his car.  As he did so, defendant appeared to be nervous.  He was immediately patted down for weapons with negative results.  Officer Williams then began talking with defendant, explaining to him why he’d been stopped, describing the traffic infractions.  Officer Williams later testified that defendant was sweating even though it was not a “really hot night.”  The Court noted in a footnote (fn. 4), however, that the body camera failed to show any sweat on defendant.  At the four minute and 20 second mark into the stop, Officer Williams asked defendant if they could “take a quick look” into his car.  Defendant responded by questioning whether they had the authority to do so based upon no more than a traffic infraction.  A short legal debate resulted between defendant and Officer Williams during which defendant suggested that he just “get a ticket and get on my way.” Officer Williams later testified that defendant was “getting very hostile” and “very confrontational.”  However, Officer Williams’ body camera showed that “at no time during the stop did (defendant) act angrily, raise his voice, make any aggressive movement, or behave in any objectively hostile manner.”  At the six-minute mark, Officer Williams asked again for consent to search defendant’s car.  Upon defendant declining once more, he was immediately handcuffed. Officer Williams told defendant that the handcuffing was “for my safety because of the way you’re acting,” and “because you’re being very aggressive;” accusations not supported by any body camera evidence.  At about eight minutes into the traffic stop, Officer Williams asked over his radio for the assistance of a “narco dog.” Officer Diep, the narcotics dog’s handler, testified later that he had been informed in advance of defendant’s detention that his presence would be required.  As they waited for Officer Diep’s arrival, Officer Williams began questioning defendant about whether he had been using drugs.  Defendant denied any such drug use. Officer Williams conducted two quick tests, examining defendant’s eyes with a flashlight and checking his pulse, completing both of them at the nine minute and 45 second mark.  Officer Williams later testified that he was “concerned” because defendant kept opening his eyes despite being told to keep them closed for approximately 30 seconds.  The Court noted in a footnote (fn. 6) that this did not occur; i.e., that defendant kept his eyes closed as instructed.   For the next three minutes, Officer Williams continued to talk with defendant, telling him that he (the officer) suspected he (defendant) was under the influence of drugs because he was “acting strange.” Officer Williams continued talking to defendant, explaining to him at length his reasons for the traffic stop and the procedures that police follow during a traffic stop.  Officer Diep and his narcotics dog finally arrived at the scene some 12 minutes and 45 seconds into the stop.  After briefing Officer Diep about the situation, Officer Williams asked him to “just run the dog by the car real quick.”  It was now 13 minutes into the stop.  At the 14-minute mark, Officer Williams made a request over the police radio to run defendant’s name “statewide for any convictions.”  The dog sniff continued until about 18 minutes and 45 seconds into the stop, after which (at 19 minutes) Officer Diep told Officer Williams that the dog had alerted at the rear passenger area on the driver’s side.  Officer Williams shut off his body cam at this point and began searching defendant’s car.  As he did so, another officer at the scene—Officer Burnett—explained to defendant how pretext stops worked, telling him that as a member of the department’s Metro Unit: “I generally don't make traffic stops to give tickets. I don’t. That's not my intent. That’s not why I'm making the stop. My intent is to make traffic stops, is to, and then in turn prevent crime from happening. Which is, i.e., guns, gangs, narcotics. I mean, warrants, parolee, probation, making sure they're doing all their things right.”  (Why Officer Burnett felt it necessary to give defendant a free education on the theory of pretextual stops is unknown.)   The search of defendant’s car resulted in the discovery of $6,200 hidden in a compartment under the driver’s side of the dashboard.  A secret compartment under the back seat was also found, but couldn’t be opened.  So the car was impounded with the secret compartment later being forced open.  Inside this compartment, officers discovered some 1,132 grams of cocaine, 73.5 grams of methamphetamine, and another $10,000 in currency.  No warrants were ever obtained.  Once the search was initiated, Officer Williams never did anything further to investigate whether defendant was in fact under the influence of a controlled substance.  No blood or urine test was ever conducted.  Defendant was charged in state court with a pile of drug possession-related offenses.  Prior to trial, his motion to suppress the evidence obtained from his car was denied.  Defendant pled guilty to all charges and was sentenced to a year in county jail and five years of probation.  Defendant appealed.
