The future world in "12 Monkeys" isn't just a dystopia, it's a cacotopia, the worst possible world. The government (such as there is) seems to function largely through the total repression of citizen's rights.
We live underground! The world belongs to the fucking dogs and cats.
We're like moles or worms.
Although the scientists (identified in the script as the Astrophysicist, Engineer, Botanist, Microbiologist, Zoologist and Geologist) seem to represent something of a ruling council, the reality is that they too are likely to be suffering the long term effects of malnourishment, vitamin deficiency, deprivation, social phobia, post-traumatic stress and paranoia:
The original script offers us a bit more of an insight into their portrayal:
COLE'S POV: Walls hidden by old headlines, articles, maps, charts...a
blackboard covered with elaborate, sophisticated formulae...surfaces
heaped with cracked monitors, gerry-rigged computers held together
with string, lasers lost in tangles of cable, ancient tube amplifiers,
a dilapidated cardboard reconstruction of a city, stacks of moldering
books and tattered computer printouts...and, seated at a long
conference table, staring at COLE, six SCIENTISTS: an ASTROPHYSICIST,
ENGINEER, BOTANIST, MICROBIOLOGIST, ZOOLOGIST, and a GEOLOGIST. They
represent a "modern" science where brilliant new ideas interface with
crude, outdated, patched-together technologies.
And also explains why they were singing to Cole, they're celebrating his achievement:
Crowded around COLE'S bed, the SCIENTISTS are concluding a ragged, out
of tune, rendition of "BLUEBERRY HILL."
SCIENTISTS : ---found my thrills on Blueberry Hill...
Seeing he's awake, SCIENTISTS break off the song and applaud.
SCIENTISTS : Well done, James! Well done! Nice going!
Congratulations! Good for you!
BOTANIST : During your "interview," while you were..."under the
influence," you told us you liked music!
