What decline in police funding? There may be a decline in city budgets generally but police are not proportionally affected: "law enforcement spending as a share of general expenditures rose slightly to 13.7% from 13.6%, according to data compiled by Bloomberg CityLab"
According to that article it sounds like yes, the average went up slightly, but that covers up the real story: some places have decreased funding and some have increased funding.
I mean ignoring everything you said right up to the end statement, that's always been the case since the police are under no obligation to protect you.
