In San Antonio, my son is having a difficult time getting into the police academy. The entry requirements appear to be designed to weed out the wanna-be's, and let the few who truly have the drive and desire to get through. I don't have details, but there are education requirements, and physical requirements, as well as the background check stuff that gets pretty detailed from what I have been asked!
Anyway, given that scenario, I see that once a person becomes a police officer, the requirements are relaxed! IOW, I see an awful lot of officers who are overweight, and probably too old to be "on the beat" in certain ways. I mean, we need the best of the best on these police forces, not what I have seen over the years.
