LMPD officer who won $450,000 settlement in whistleblower lawsuit again sues the department

How do you know it would be $2000 a month? I'm not suggesting you are wrong, just asking how you came to that conclusion. If Tier 3 is only guaranteed 4% a year (more if the market is good) but they don't have a defined benefit, then how do you know how much you will get until you are prepared to retire?
