Requesting A Warrent and making an arrest

If, after their investigation, the officers have sufficient information to believe someone has committed a crime a request for an arrest warrant may be made; however, if the crime is committed in the police officers presence an officer may arrest the person on the spot. If the officers have probable cause (enough particularized facts to lead a common-sense person of reasonable caution to believe that there is a fair probability of criminal activity) to believe a crime has been committed, the officer may submit a charging/warrant to the Prosecuting Attorney. At this stage, the Prosecutor determines whether a person should be charged with a crime and, if so, what the crime should be. If the Prosecutor determines to arrest the suspect, the prosecutor will present the warrant to the magistrate/judge for his or her signature and return it the officers to arrest the suspect.
