He may not have uttered the word 'pleb' but what part of "I'm a member of parliament and I'm too important to stop for you..." fails to embody the very essence of the word?
I think it is a trick of the brain to save memory consumption by condensing the facts of an incident into words which convey what happened effectively, in as few words as possible, like an editor does. This certainly saves time if you want to relate the story, verbally, to someone who wasn't there to see it for themself.
So, the policemens' first mistake was to deploy time-saving language. Maybe not deliberate 'spin' but, as the story goes up the management chain, progressively less interested officers, edit further. "Pleb" might have originated somewhere amongst the management.
When it got to the people with the grudge about the pay structure, they pounced on the 'p'word and 'weaponised' it, so to speak.
Victims of their own machinations, if you ask me.
