N.Y.P.D. needs to cut a few trees.
The speaker is a police officer and she did a lot of overtime to pay her depts. But NYPD didn't want her to do that and take a lot of money. So NYPD had a division officer say to her that she should stop doing overtime. And she said 'NYPD needs to cut a few trees' to a division officer.
My question is, what does 'cut a few tress' mean? I googled it, but it only says it means felling.
Maybe it means 'a curtailment in the budget'?
