I mean the general grey area around it. If total corruption is say 70.1%, then the first policeman might very well be effective. Or due to rounding only effective on commerce or shields, but not both. Every additional policeman however would be effective. So there is something that can be lost, albeit it hardly matters.You mean when the first policeman does nothing?
Mostly not. Especially since scientists are a bigger boost to science than an effective policeman.If the first policeman does nothing, I typically consider the city to be beyond salvation. Max corrupted. I do not try to salvage production or commerce from that one anymore. Am I wrong?
