The officers in question did not watch Jordan Lyon drown. They arrived after the fact. It's a large lake and the boy wasn't to be seen. What were they supposed to do? The part where they could have done anything useful was long past, time for divers to search the lake for a corpse.

It's a usual case of the media (and here particularly the BBC, disappointingly) creating a story where there is none, turning this into a general allegation against PCSOs. While there are problems about what exactly their purpose is this apparent media crusade completely misses the mark.
