You are not every police officer. Every police officer is not you.
This article lists a few cases that illustrate what I'm talking about. Among them is the case that originally brought this issue to my attention, the rape of three women that was reported via 911 multiple times and ignored.

Also in the case you're talking about, the police did nothing after the ex-husband kidnapped the daughters, whom he later murdered before opening fire on a police station. The woman was awarded a judgement which was reversed by the Supreme Court.
Special protection has nothing to do with it. It's a matter of liability over negligence.
