121 S.Ct. 1536 (2001)
-Nobody was wearing a seat belt.
-Respondent, a police officer, observed seat belt violations and pulled P over.
-P told police officer she did not have driver’s license an insurance documentation because her purse had been stolen the day before.
-P was arrested and booked, charged with driving without her seat belt fastened, failing to secure her children in seat belts, driving without a license, and failing to provide proof of insurance.
-P pleaded no contest to the misdemeanor seatbelt offenses and paid $50 fine; the other charges were dismissed.
Holding: No. Judgment affirmed.
Procedural History: Suit initially filed against the City of Lago Vista and Chief of Police. The City removed the suit to federal district court which ruled the Fourth Amendment claim “merit-less” and granted the City’s summary judgment motion. The court of appeals affirmed.
-If a police officer has probable cause to believe that an individual has committed even a very minor criminal offense in his presence, he may, without violating the Fourth Amendment, arrest the offender.
-P has cited no particular evidence that those who framed and ratified the Fourth Amendment sought to limit peace officers’ warrant-less misdemeanor arrest authority to instances of actual breach of the peace.
