The headline is a lie. The law bans police pursuits without supervisor approval in some circumstances. In as much as a police pursuit is often a danger to the public, the ban itself arguably protect the public.
As to police not protecting the public, however much we may want to blame looney left politicians for it, the blame lies solidly with the Supreme Court, thanks to the precedents in The Town of Castle Rock v. Gonzales and Deshaney v. Winnebago County Department of Social Services. (And Scalia wrote the majority opinion in the first of those.)
