I am probably 100% wrong, but isn't there something about how your police pension is based on your final three years of work?
There is an arrangement where the guys getting ready to retire get a ton of overtime to inflate their final three years of salary, so when their pension calculations are done, they get a big $$$ boost?
This is just what I heard, and I don't have anything to back this up...
Edit:
Retirement benefits: 3% of final compensation per year of service at age 58, with a maximum of 90% benefit based on years of service.
