Reasonable suspicion is the level of justification that lets an officer briefly stop and investigate when there are specific, articulable facts that something may be afoot, along with reasonable inferences from those facts. It’s enough to justify a short detention and questioning, but not to arrest or conduct a full-blown search. The key is that the facts must be concrete enough to explain why the stop is reasonable, even if they don’t prove guilt.

Probable cause is a higher standard. It requires enough facts and circumstances to lead a reasonable person to believe that a crime has occurred or that the person is involved in a crime, supporting more intrusive actions like arrest or a search. It’s not about proving guilt beyond a reasonable doubt; it’s about showing a fair likelihood based on the totality of the circumstances.

In field actions, you start with reasonable suspicion to stop or briefly detain someone. If additional evidence emerges that points more convincingly to involvement in a crime, those facts can accumulate into probable cause to arrest or to search the person or place, depending on the situation.

For example, noticing a person matching a robbery suspect’s description, acting nervous, and in a location and moment that makes the situation suspicious provides reasonable suspicion for a brief stop. If the person then has stolen goods on them or there’s other solid evidence tying them to the crime, those facts may establish probable cause to arrest.
