Ok this gave me the workaround.
I can't decrease your budget, so your budget is x. Be prepared because 10 years from now your budget will still be x. This year you can have no more than y% of your staff carrying weapons, that number will decrease over the next 10 years. You can spend no more than z% of your budget on new weapons, to include ammunition and tactical vehicles. You must spend at least c% on improving your standing with historically oppressed groups/neighborhoods and you must spend at least d% on things like social workers, negotiators, and other trained staff to help you better de-escalate situations. The things that help you to de-escalate will need to be documented because those are the areas of your business that will see incremental growth as we ramp down your ability to pay for armed staff and weaponry.
I've now started down the path of successfully doing what needs to be done without touching the overall budget.
