Actually this is starting to make a little more sense regarding the chain of communications.
PC West was being updated by the Information Room (I/R). The information Room (Ivor Norman) was being updated by the occupants of CA07 (Saxby, Myall & Bews) up until 08:39 when CG32 became the Control Vehicle, CA07 must have been updated by Adams up until that time.
Who is in CG32?
The earliest timed mention of 5 dead bodies is in the I/R log at 08:09, so that must have been communicated from the firearms team (who?) to Adams, to the occupants of CA07, to the I/R and finally to West.
Adam states that the firearms team reported to him that the scene was safe at approx 08:15, so from the first mention of five bodies until the scene reported as being made safe is approx. six minutes, give or take.
I don't buy into any theories based on the use of the English language, so whether somebody uses a past tense or a present tense or a phrase like "no not at all", is not in any way (in my opinion) an indication of telling the truth or telling a lie.
Again in my opinion. Just making it absolutely clear to absolutely everyone who might suggest otherwise, that this is just my opinion. Okay? All understood?
