I think he was in the right. I tell myself all the time I need to shape up. It's good for your health and its good for the job. He wasn't singling people out or saying it in a malicious way. This type of job should have fitness tests more often. What happens when police get older and less fit- they don't normally go patrolling the streets anymore, they take more specific jobs with less fitness needed. Maybe he should have made up anonymous flyers as if the memo was some sort of fitness advertisement.
