The London Corporal Punishment School is a draconian establishment, quietly ignored by the education authorities
and staffed by those whose callous outlook prohibits employment elsewhere.
The pupils (read 'inmates'), generally abandonned there, cluster in gangs of like-minded fellows for a soupçon
of protection. As much from the other gangs as the teachers.
That's the fantasy background. In a sense it's window-dressing for an excuse to punish pupils, but with a
different flavour from other rationales, such as a caning competition.
The LCPS was conceived as a pupil-led (cf teacher-led) extension to
the BDSM school scene, in order to encourage rôle-play.
The gangs are a grass-roots movement, similar to houses, but instigated by the pupils instead of the teachers, and serve
the function of providing a pupils social peer-group. (Not that the teachers
are a cohesive, close-knit group!)
Whilst academic achievement is left somewhat behind (and sporting activity largely confined to the Heavy gang), the gangs
provide an outlet - a prop to occupy their time.
