There is one important factor like police funds from 0-100%, going down daily by 10%.
Every police station decrease crime rate by funds*0.2%, so when police funds are at 100% one police station should decrease crime by 2%.

at this moment police funds are at 50% and effect should be -1%...
at 0%, without funds police doesn't work :D

Police funds will be refilled by president, for now emperor gerber :) refills it.

This part is ready for government update, and game president chosen by players will decide about refilling police funds. Refilling police funds will also apply one day 10% tax on income.
