When a police officer leaves their department because of misconduct, there's no easy public way for people to know if they're rehired elsewhere in law enforcement. One of the most notable recent cases was Timothy Loehmann, the former Ohio officer who shot and killed Tamir Rice in 2014. Loehmann was fired from the Cleveland police force in May 2017 after an internal review panel investigating Tamir's shooting found he lied or omitted crucial information in his application's personal history statement. In 2018, Loehmann applied to, was hired for and then withdrew his application to the police department in Bellaire in eastern Ohio. This would have been his third department in a five-year span.The police union in Cleveland has since filed an appeal to reinstate Loehmann. He was not charged in Rice's death. Currently, there is nothing stopping these officers -- whom some experts called "wandering" or "second-chance" officers -- from going to another state or a smaller department within the same state. Some law enforcement experts tell CNN there needs to be greater federal oversight to track officers who have been involved in misconduct, similar to how the National Practitioner Data Bank tracks misconduct and malpractice payments for health care professionals.
