What does "reasonable suspicion" allow an officer to do in South Dakota?

Reasonable suspicion is a legal standard that allows law enforcement officers to stop and question individuals based on specific, articulable facts or circumstances that suggest criminal activity may be afoot. In South Dakota, as in other jurisdictions, this standard is less demanding than "probable cause," which is necessary for making an arrest or obtaining a search warrant.

When an officer has reasonable suspicion, they can approach a person, ask questions, and engage them in conversation to gather more information. The key aspect of reasonable suspicion is that it is based on observed behavior or facts that would lead a reasonable person to suspect that the individual may be involved in criminal activity. This practice is crucial for proactive law enforcement while still respecting individuals' rights, as it provides a balance between public safety and personal freedoms.

The other options provided do not align with the definition or purpose of reasonable suspicion. Making an arrest without evidence requires probable cause and not just reasonable suspicion. Conducting a thorough search without a warrant typically requires probable cause and is subject to the Fourth Amendment protections against unreasonable searches and seizures. Using excessive force is not permissible under any standard of suspicion and is contrary to law enforcement protocols that promote proper use of force.
