Im a police officer and I'm all for it to be honest. I also think the level of fitness required to join now (much lower than when I joined) is waaaay too low. Some roles in the police already require regular fitness tests and higher levels of fitness to do e.g firearms, dogs, public order etc.
Some of the stuff quoted there is total poo pop though. No idea where they got the stats from for the percentage of overweight officers. Plus it goes on bmi rather than any sensible measure of fitness or proportion. I'm 6'1 and 14 stone but I also have a low body fat measurement and would be classified as one of the fatties.
I predict the other stuff about direct entry at Inspector and Superintendent level will backfire on them spectacularly. You wouldn't employ a vet as a consultant neurosurgeon. Madness.
