Should police officers be allowed to be overweight

So before anyone pipes up I’m not fat shaming anyone but the police is a very physical job and I think they should only have people that have a good level of fitness. I am constantly watching police show documentaries and the police officers are always overweight and a lot of them old and I have seen police officers in real life like this aswell and they are not able to do their job properly. Alot of people that commit crimes are able to run away for miles therefore someone over weight or old isn’t going to be able to Cath them and that’s a reason why so many criminals don’t get found or brought to justice. Just my opinion
