This matter could easily be resolved, simply by PS Bews repeating what he told the control room when the police and Jeremy returned to the patrol car, after the sighting...
Additionally, the person who recieved the radio message from CA07 at that time, could also confirm what PS Bews said then...
Furthermore...
The person who the control room contacted to deploy the firearms officers to the incident needs to be looked at...
And also...
The firearms officers themselves, need to be asked, what they were told, and by whom they were told to go to the incident...
It should be obvious to everyone, that a senior officer deployed the firearms team to the incident, but so far we have not heard what he was told, or what instructions he gave to the firearms officers when he deployed them...
Finally, there exists a log of what PS Bews told the control room at 6:02am (from the scene) but its contents are being deliberately withheld...
Therefore, should anyone of these (above) elements be disclosed, the truth about the "trick of light", would easily be exposed as a lie...
