Probable cause is the level of evidence held by a rational and objective observer necessary to justify logically accusing a specific suspect of a particular crime based upon reliable objective facts. It is more than mere suspicion but sometiomes less than the amount of evidence required for conviction.

I think "probable cause" is the legal term.
Probable cause refers to the standard by which a police officer has the right to make an arrest, conduct a personal or property search, or to obtain a warrant for arrest. It is also used to refer to the standard to which a grand jury believes that a crime has been committed.Added: Probable cause is the standard used in justifying certain police actions. For example, police need to have probable cause to believe evidence of a crime exists when making an arrest or in requesting a search warrant.Probable Cause is more than mere suspicion but less than the amount of evidence required for conviction.For example: A police officer may use "probable cause" to arrest someone for attempted theft when he finds someone trespassing on private property late at night wearing a stocking mask. Using this probable cause as justification for stopping the subject and, searching them, they find them in possession of burglary tools, thereby justifying the probable cause forcible stop.
A arrest warrant is an order by a judge, to the police, to bring a person before the court to answer for criminal charges. Arrest warrants (with some exceptions, such as Ramey warrants in California) are only issued after the judge has reviewed a probable cause affidavit that describes the probable cause for the arrest and agrees that the arrest is reasonable. In a probable cause arrest, also known as an "on view" arrest, the arresting officer makes the decision to arrest the person on the spot. The decision will later be reviewed by the officer's supervisor(s) and by the prosecutors office before criminal charges are actually filed and the defendant is arraigned.
Probable cause is typically established when there is enough evidence to suggest that a crime has been committed or is about to be committed. This evidence can come from witness statements, physical evidence, surveillance, or other investigative techniques. Probable cause is required by law before a search or arrest can be conducted.
