Final answer:
Some examples of vehicle stops that do not require any particularized suspicion include random security checks, traffic violations, and probable cause. So, the correct answer is 1), 2) and 3).
Step-by-step explanation:
Some examples of vehicle stops that do not need any particularized suspicion include:
Random security checks: Law enforcement officers may conduct random security checks on vehicles without any particularized suspicion. These checks often occur at border crossings or at transportation hubs.
Traffic violations: Police officers can stop a vehicle if they witness a traffic violation, such as running a red light or speeding. These stops do not require any additional suspicion.
Probable cause: If a police officer has probable cause to believe that a crime has been committed or evidence will be found in a vehicle, they can conduct a search without any particularized suspicion.
Thus, the correct answer is 1), 2) and 3).
