A Davis police officer issued a citation to a driver for excessive horn use shortly after 10 a.m. Thursday near Cowell Boulevard and Lillard Drive, during a U.S. Immigration and Customs Enforcement operation in the city. City officials are reviewing whether the officer violated any city policies or regulations.
Why it matters
The citation has drawn attention because it occurred during a federal immigration operation that city officials said they were not asked to assist and that the City of Davis does not support. The review will determine whether the officer's conduct met city standards.
The officer's citation for excessive horn use is the subject of an administrative review by city officials, who have not said whether any policy was violated. Whether anyone was detained during the federal operation remains unconfirmed by the city.
The players
U.S. Immigration and Customs Enforcement
ICE is the federal agency responsible for immigration enforcement and criminal investigations within the United States.
Davis Police Department
The Davis Police Department is the municipal law enforcement agency serving the city of Davis, California.
The details
The officer pulled the driver over after spotting excessive horn use near Cowell Boulevard and Lillard Drive and issued the citation. City officials learned at about 9 a.m. that federal agents planned an operation in Davis using unmarked vehicles, though ICE did not request local assistance or disclose the operation's location.
Timeline
About 9 a.m. Thursday: City officials learned federal agents planned an operation using unmarked vehicles.
Shortly after 10 a.m. Thursday: The officer issued the horn citation near Cowell Boulevard and Lillard Drive.
About 10:40 a.m. Thursday: Federal agents left Davis.
Legal Context
The city's refusal to assist ICE and its stated opposition to the agency's activities fit within California's limits on local cooperation with federal immigration enforcement. The administrative review of the officer's horn citation tests how a routine traffic enforcement action is handled when it occurs during a federal operation in a sanctuary-oriented jurisdiction.
Davis residents driving near federal enforcement activity may see police traffic enforcement continue as usual, with citations issued for vehicle code violations. The outcome of the city's review will indicate how officers are expected to conduct themselves when federal operations are underway.
The takeaway
Residents who witness police or federal enforcement activity can document the time, location, and officers involved and report concerns to the city. The city's administrative review may clarify what standards apply to officers during such operations.
