Cop FAKES a Sobriety Test — Then Gets CAUGHT Lying in Court
Flawed Execution: Deputy Caught on Camera Fumbling Sobriety Test Under Oath
Preview
When an officer relies on a subjective eye test to arrest a driver, precision is everything. Watch how a defense attorney methodically dismantles a deputy’s case in court by comparing dashcam footage to official NHTSA guidelines. From rushed procedures to a complete inability to explain the science, this stunning suppression hearing exposes a flawed arrest from the ground up.
The New Year’s Day Stop
The incident unfolded on January 1, 2026, when Deputy Jeff Carroll of the Burnett County Sheriff’s Office responded to a single-vehicle accident in Wisconsin. Finding an SUV stuck in a snowy ditch with its front tire still spinning, the deputy made contact with the driver, Antonio Morales. Smelling alcohol and noting glassy eyes, Deputy Carroll administered standard field sobriety tests.
While Morales passed the walk-and-turn and one-leg stand tests or showed minimal clues, the deputy claimed he failed the horizontal gaze nystagmus (HGN) eye test with a “perfect score” of six out of six clues. That single assessment served as the primary justification for the OWI arrest.
The Cross-Examination Collapse
Months later during a suppression hearing before Judge Melissa Mogan, defense attorney Daniel Chapman put the arresting deputy on the stand. Armed with the National Highway Traffic Safety Administration (NHTSA) training manual, Chapman asked the deputy to explain the mechanics, timing, and scientific basis of the HGN test.
The results were disastrous for the prosecution. Deputy Carroll could not recall key parameters, admitted he didn’t know the science behind why the test detects intoxication, and failed to explain appropriate finger-movement speeds.
When Chapman played the stop’s video evidence frame by frame, it revealed that the critical eye assessments were rushed, taking a mere 15 seconds instead of the proper duration.
A Crucial Legal Victory
Reviewing the video alongside the official guidelines, Judge Mogan ruled directly from the bench that the HGN test was performed inaccurately and improperly. By discrediting the centerpiece of the state’s probable cause argument, the court delivered a major win for the defense, proving that subjective police tests must withstand rigorous objective scrutiny.
