I would hope he was undergoing regular medicals as standard, for his employer. I read somewhere that he had failed a medical but I think that was many years back when he was working at Dungeness. I'd wondered whether he failed due to physical issues or mental ones, but we may never know.
The truth is that employer medicals don't always catch everything. Some of them are not robust at all, especially if they are an "update medical" with comprehensive ones only required every few years. (I don't know what the Met Police requires.) I work in a profession where medicals are required from time to time and have seen how people are able to get those to pass even where there is an issue that should be reported (I do not recommend or condone this!).[/QUOTE]
Bbm - Unfortunately I see this in my line of work as well , some things are just not screened for or evaluations made .
But then again , I don't know Met Police standards , not even as far as recurring medicals .
