I used to work in law enforcement. Its a tails you lose, heads I win situation for the police.
Generally speaking police leadership likes to justify their jobs with "crime numbers are going down" its an easy "objective" way to show they are effective and its the primary metric they try to game. Then its ask for more budget because we can make numbers go even more down with more resources.
When crime numbers go up its "we need more resources!". Which is the traditional refrain of well every government agency that is not succeeding in their mission. And succeeding in their mission. Every agency is gonna ask for more money. Always and forever.
Line officers dont care as much about overall metrics but have different incentives put on them. Their immediate leadership want numbers to look good too.
No matter what way the number goes up or down there is a ready narrative that involves we need more budget. If number goes down, its my leadership caused this. If numbers go up then its external things fault.
Typically speaking police chiefs like numbers to go down because it reflects well on them. Detectives like persuing cases that result in convictions because it makes them look good and promotable. Zone leadership likes numbers to go down because it makes them look good and promotable. If you are the Captain of the highest crime rate precinct you are less likely to get promoted than the one with a better rate. This trickles all the way down.
