The difference between probable cause and reasonable suspicion is that probable cause requires specific and articulable facts that a reasonable person would believe demonstrate the guilt of an individual, whereas reasonable suspicion only requires a law enforcement officer to have some level of suspicion that criminal activity may be taking place. While reasonable suspicion can rely more heavily on speculation or intuition, probable cause also requires factual evidence to support it. Moreover, in order for an arrest or search to take place based on probable cause, a warrant must typically be issued, whereas searches and arrests based on reasonable suspicion do not require a warrant.
