In Texas v. Brown, 460 U.S. 730, 103 S. Ct. 1535, 1540, 75 L. Ed. 2d 502 (1983), the Court expounded upon the requirements of probable cause: Probable cause is a flexible, common-sense standard.

Ct. at 1543. In that case, a police officer who had stopped a vehicle at a random license checkpoint saw the driver drop a knotted balloon onto the floor as the officer approached the car. When the driver opened the glove box to look for his license, the officer changed his position to get a better view of the compartment and saw that it contained loose white powder, small plastic vials, and a bag of balloons. The Court held that the officer, who through experience with drug cases knew that offenders frequently used balloons of this type as drug containers, lawfully seized the balloon that the driver had dropped onto the floor of the vehicle.
