This is the characterisation or Experience Scene for Gordon Sinclair.
Gordon is one of a team of Special Branch operatives tasked with raiding three houses ‘infested with communist political students’ from the London School of Economics.
Bursting into the designated rooms, Gordon discovers a trio of youths. They plead with Gordon, and persuade him of the injustice of his orders; he retreats. His report of the operation makes no mention of the encounter.
