Well obviously police cars would not have been dispatched before they were made aware of an incident. :D
He's claimed two different versions of whether he called Julie before or after the police.
He called Julie first, but couldn't talk for long because he had to call the police?
He called Julie second because he was p***** off at the police?
Going from her flat mates testimony and that I don't recall seeing Julie mention that JB had said he'd called the police when he spoke to her, it would appear to me that he spoke to Julie first and the police second.
Ha, ha!! The premise being that Neville called before Jeremy and so cars were dispatched in line with HIS call

.
I agree that he spoke to Julie first, then the police. In his first statement he doesn't mention calling Julie at all.
Also if we're pretty sure that the call to Bonnet (from West) was at 03:26 and the 03:36 written by West on Jeremy's log was a mistake the whole call from Neville and cars being dispatched as a result of this call, falls flat on it proverbial? It's pretty obvious that there was only one call and the cars dispatched were as a result of this call - the call from Jeremy, which would have occurred around about 03:20 (obviously that's approx). If he spent 10 mins looking for the station number nd also made a call to Julie, the timings just don't add up.
