You have 281 pops on a world with no precincts and no crime?
The great world-city of Eledtopia stands at present at 293 pops, and 0 crime after modifyers.
It is the capital of a fanatic spiritualist / xenophile megachuch, and its govenour is corrupt. The world in total preesntly generates 70 base crime from its population, +25 for the govenour. It has 21 foundary, and 11 residental arcologies, and Ivefinished all tradition trees.
That 95 is then reduced by 90 from enforcer sfrom the capiltal building -15 from artifical moral codes and a further 18 for the corrupt Govenour's skill as he's level 6.
The rares at which enforcers reduce crime, aginst which it is created innately, are out of balance. Even with the planet spanning agora that proviide so much trade and so many ameanites, infact if anything becase of the trade, I'd expect... honestly I'd expect to have to do
something about the crime... say not wipe the Psi corpbuilding a while back.
