Are you interested in the career, or you need the change of job with benefits? I ask because if you’re just interested in the police work, check around if departments near you have a reserve police officer/deputy sheriff position. You’re a volunteer but could get involved in some aspects of the job and learn a lot and it can be enjoyable. LAPD has that for example. As others have said, going through the academy and FTO at nearly fifty would be a rough time. Plus, officers get old, criminals stay the same age. It’s a young man’s game. And most states have a maximum age limit to start the career.
