Couldn’t we build something like this in Kensington?

In the two-part episode of Star Trek: Deep Space Nine entitled Past Tense, Part 1 and Part 2, a transporter accident lands Commander Benjamin Sisko, Dr Julian Bashir, and Lt Commander Jadzia Dax in San Francisco, in the year 2024. From Wikipedia:

Sisko and Bashir are found by a pair of police officers, who believe them to be vagrants and warn them to get off the streets. They are escorted to a “Sanctuary District”, a walled-off ghetto that is used to contain the poor, the sick, the mentally disabled, and anyone else who cannot support themselves.

Well, who would have thought that it would be so prescient!
