Non joke answer: A bunch of reasons. Many precincts are understaffed, so they need all the hands they can get. The police union is huge and makes it extremely difficult to fire even the most homer-simpsonian individuals. Many of the hugely obese cops are assigned to “light duty” meaning the most exertion they face is paperwork, manning the public information desk and or doing things like serving writs (in some cases you’re allowed to wear the uniformn even if you’re not a bonded officer, which is absurd). Additionally, fitness requirements are actually fairly rare across the whole spectrum of law enforcement - It’s surprisingly rare to see them for any positions besides uniformed patrol officer, even detectives or etc. aren’t always required to pass them - and even when you do, they’re usually pathetically easy to pass.
Lmfao dude thats propaganda, the marines are teenagers who’ve had “loyalty above everything” kicked into their heads since they joined up. At best they just stand around and don’t do anything, but take it from a former marine, that situation is unlikely.
