Calling 999, unless the caller is a child in need of support, is understood to guarantee a much faster response that calling a local number...................but he never gave it a chance, did he?
There was no requirement given the then known circumstances for Jeremy to call the police by using the '999' system. In any event, Jeremy's call to PC West was recorded on audio tape, similarly to what occurs using the '999' system. It seems to me, that the same units which attended the scene, would in any event have been the same police units which would be sent to the scene, had Jeremy thought to dial '999' instead. That being the case, I doubt whether someone on a switchboard could have got PC West, or the occupants of CA07, and CA05, to act any quicker than they already had done? Not only that, but what difference would Jeremy dialling 999 have made in any event after the call from Neville had got cut short? Since, by that stage (3.26am) Neville was already talking to the police, hence why the occupants of CA07 were deployed to the scene a minute prior to Jeremy contacting Chelmsford police station via the landline route. Jeremy dialling '999', as soon as the line between himself and Neille ended abruptly wouldn't have been an option for Jeremy. He might not have had that option until after he had tried to ring Neville back at least twice, and been met with an engaged tone on both occasions. So, at that stage, what good would it have done if Jeremy had dialled '999' at say 3.26am, considering that Neville was already speaking to the police by then (see (C1) Communications log, 3.26am)?
Nothing which Jeremy could have done any differently, was capable of alerting the police to deal with the unfolding drama, any sooner, because Neville was already in contact with police, regarding the same matter!!!
