I'm not sure which of my points you think wasn't well made.
I can't pretend I'm too young to have been at the Bar when the 'Judges Rules' applied but, not having had reason to look at them for almost 20 years, I don't remember them in any detail.
However, assuming your recollection is correct, a "Duty to Assist Police" doesn't mean there is a duty in law to report all suspected offences to the police. There may in certain circumstances be a moral or civic obligation to do so, but that's a different matter.
Even if the pilot is guilty, that doesn't mean many others involved aren't deserving of criticism.
I'm curious. Your profile says your occupation is 'air traffic' but you seem to have a 'police constable' approach.
