The Fourth Amendment of the United States Constitution protects citizens from unreasonable search and seizure. Part of this requires a police officer to have a reasonable suspicion of criminal activity in order to conduct a vehicle stop or any other search of a suspect. As a Massachusetts OUI attorney, this often becomes an important issue because if a police officer does not have this reasonable suspicion and conducts a vehicle stop or search, all evidence collected from this illegal search will have to be thrown out and will usually end in a dismissal of the case. Without a reasonable suspicion, a stop of a vehicle or search of a person will be considered illegal and unconstitutional.
Determining whether an officer’s stop was conducted under reasonable suspicion is often a topic that is difficult to determine. The Iowa Supreme Court recently took on the issue of whether an anonymous tip about a potential drunk driver can create this reasonable suspicion in Iowa v. Kooima. This case involved the defendant who was at a steakhouse for over an hour with several other gentlemen after a day of golf. Another patron recognized the men as prominent businessmen from the area. He proceeded to call 9-1-1 and describe the car and reported the license plate number. The anonymous caller told the operator that all the men were drunk and were going to leave but never gave any information about what they drank or how he knew the men were intoxicated. Despite the lack of details and not seeing the men drive, the dispatcher told officers in the area to be on the lookout for the car.
The officers followed the defendant and he never made any traffic violations or mechanical violations. Based solely on the tip, the police conducted a stop, gave the defendant a breathalyzer and field sobriety test and arrested the defendant on drunk driving. The defendant claimed the stop was not authorized but was convicted of drunk driving. The Supreme Court disagreed and ruled the stop was not authorized.
