FYI, KFC Gatwick is on land under statutory control as it is within the airport boundary and therefore is not relevant land for the purposes of PoFA.
What this means is that under no circumstances should you, the Keeper, identify the driver. If you do identify the driver, you have thrown away what is known as a "golden ticket".
MET will try and argue that the land is private and so is relevant land. However, we have maps of the Gatwick Airport boundary and, even if the land is private, it does not matter as it is within the airport boundary and subject to airport bylaws and therefore, not relevant land for the purposes of PoFA.
So, don't blab the drivers identity, inadvertently or otherwise, as there is no Keeper liability.
