How are warrant arrest and probable cause arrest alike and different?

Answer 1

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.
