Probable cause is the minimum amount of information necessary to indicate that a crime has occurred or is occurring. It is a legal standard used to determine whether a search or seizure is permissible.
Step-by-step explanation:
Probable cause is the minimum amount of information necessary to cause a reasonable person to believe that a crime has been or is being committed. It is the legal standard for determining whether a search or seizure is constitutional or if a warrant should be issued. For example, in Terry v. Ohio, the Supreme Court determined that police can stop and frisk a person if they have reasonable suspicion that the person has committed or is about to commit a crime.
