What is Probable Cause?

Probable cause is a standard defined by the Fourth Amendment of the U.S. Constitution that must be met before police can conduct a search, make an arrest, or obtain a warrant. It is a reasonable belief, based on facts and circumstances, that a crime has been committed and that the person being arrested committed it, or that evidence of a crime will be found in the location being searched.

The standard requires more than a hunch or suspicion, but less than the evidence needed to convict someone at trial. For example, suppose a police officer stops a vehicle for speeding and smells a strong odor of alcohol on the driver’s breath as well as bloodshot eyes and slurred speech. These observations can establish probable cause that the driver is operating a vehicle under the influence.

What is Reasonable Suspicion?

Reasonable suspicion is a lower legal standard that permits a police officer to briefly detain a person for investigation. It does not require the strong belief and evidence needed for probable cause, but the officer must be able to point to specific and articulable facts that, when combined with rational inferences, suggest that criminal activity is taking place or is about to occur.

This standard allows police to perform a limited intrusion of an individual’s rights, such as a brief stop and frisk. For example, if an officer observes a person hiding an object in their waistband while quickly walking away from the scene of a reported break-in, the specific behavior and location provide sufficient grounds for the officer to stop and briefly question the individual. The officer’s actions must be based on concrete, observable behaviors, not a general feeling.

Do Police Need Probable Cause or Reasonable Suspicion to Arrest Me in MI?

In order to make an actual arrest, law enforcement officers must have probable cause. This is a fundamental requirement under both the Fourth Amendment and Michigan state law. An arrest based solely on reasonable suspicion could be deemed unlawful, and any evidence collected as a result would likely be inadmissible in court.

However, police may initiate a temporary detention, often called a Terry stop, based on the lower standard of reasonable suspicion. This allows officers to briefly stop, question, and potentially frisk a person if they reasonably suspect the person is involved in criminal activity and may be armed. The important distinction is that this is not an arrest. If the investigation during the stop reveals sufficient facts, the officer’s reasonable suspicion can elevate to probable cause, justifying a formal arrest.
