A police officer position is an entry-level position unless it is advertised otherwise. As an entry level job there is no experience required. Someone with police experience may have an advantage during the oral board interview as they can answer situational questions based on real life experiences. One of the risks in hiring new officers is that the new hire who has no experience will decide that being a police officer is not right for them. As they have no experience they were not able to make this determination until after they started on the job. A police officer with experience already knows what they are getting into.
