It doesn't appear that the "copious quantities of paperwork" is a punishment. It's more like a reward - the same pay for an office job.
Don’t mistake this for defending bad acting cops but
essentially accusing people of signing up for a job where
they would rather do paperwork than be in the field
borders on asinine. I work in a similar field where negative
interaction with people requires report writing before
one goes home after shift. Nobody wants to invite extra
paperwork upon themselves. Those that might would
be called “office staff” and that is where they would stay.
