While Ohio sets physical standards for applicants, very few departments in my area have a standard that one must maintain. My dept. has brought up the idea of a fitness test as an elective, incentive-based program, but hasn't come close to implementing it. SWAT members do get tested biannually, however. The test consists of a timed run, BP, weighted pullups, situps, and an obstacle course. In the meantime, patrol has quite a few guys who have to force themselves into their vehicles. I would like to see something implemented, but all of the politics have prevented it. I am not saying that fat guys have no business being cops, or should be punished, but I think it would be beneficial to at least give people some incentive to not be morbidly obese. Actually, I would like to see the requirements for application tightened up a bit, too, but that would limit diversity hires.
Oddly, there are a couple of fat fucks who have some serious wheels on them, and a couple of fitness-model wannabes who never seem to catch anyone. Of course, nine out of ten times, the chase isn't worth it, as the guys who run usually do so for the most trivial of offenses. But, I digress.
