According to scipio_usmc, it would have taken a couple of minutes or more [for Jeremy] to explain his story to Pc West in full and to give West time to write it all down. According to Caroline, Bonnett recorded a time of 03:26, West obviously called Bonnet 'after' Jeremy had called and so Jeremy HAD to call at least four or five minutes before that.
Why these somewhat different guesses as to how long it took for Jeremy to give West the details he logged? Pc West was asked about this and said twice that it took less than a minute. Moreover, if one creates a plausible re-enactment of the call, it is consistent with what Pc West claimed. Even if Pc West incorrectly estimated the time, giving only half of the actual value, that would still mean that the correct value was under two minutes. Pc West was confident he spoke to Bonnett for less than three minutes. This is consistent with police statements that say they were told to go to WHF at about 03:30, though there isn't any explanation offered as to why they finally departed at 03:35, five minutes after being told to go.
However, Pc West and Malcolm Bonnett contradict each other regarding who despatched car CA07. Pc West stated he called Bonnett not to ask him to send a car, but to find out which police station covered WHF. Pc West also states he spoke to Witham by radio after being told by Bonnett that WHF was covered by Witham police station. This indicates that Pc West caused car CA07 to be sent to WHF. However, Malcolm Bonnett said in his statement "On completion of the conversation with Pc 1990 I called a Mobile Police car identified by the Call sign Charlie Alpha 7 and sent that vehicle directly to the scene of the alleged incident at White House Farm, Tolleshunt D'Arcy." What's interesting is that this account is not supported by what the officers who were despatched put in their statements. They said they had just returned to base and were no longer in car CA07 when told to go to WHF. Moreover, it took them about five minutes to return to their vehicle and use their radio to say they had departed. Also, Bonnett seems to have no recollection of being asked by Pc West which police station covered WHF. Clearly, Pc West and Malcolm Bonnett cannot both have been giving the truth.
