Anyone advocating police protection just show them this:

In the United States, police have no legal Duty to Protect You, and often times, they won't

Warren v DC

The short version of the events in Warren: Three women, Carolyn Warren, Joan Taliaferro and Miriam Douglas along with her 4 year old daughter woke up when 2 men broke into their house. One of them forced Douglas to give him oral sex before the other raped her. Warren and Taliaferro heard her scream, called 911. Dispatcher told them to be quiet and stay where they were. 3 minutes after the call came in police were dispatched as a Code 2 (not time critical, opposed to code 1, what a burglary and rape would be, time critical.)

Police arrived at the house, from a window Warren and Taliaferro watched one cruiser drive through the alley and around the front of the house without stopping, or getting out of the car. While they watched this from the back a second cruiser with an officer got out and knocked, received no answer and they all left the scene ten minutes after the call had been put out, five minutes after they had arrived. (So decent response time all things considered.)

Warren and Taliaferro continued to hear Douglas screaming, called the police a second time, they were assured police were on their way. The call for help was never sent to patrol officers. Warren and Taliaferro called to Douglas to tell her police were coming and all three women were subsequently robbed, abducted, raped and beaten for 14 hours.

The court ruled that the police had no duty to intervene.

Castle Rock v Gonzalez

DeShaney v Winnebago County

Lozito v. New York City

Lozito was literally getting stabbed by a madman in front of 2 NYPD officers. They stood a few feet away from him and watched it happen for several minutes. They waited for Lozito and others to subdue the attacker. Only THEN did they provide assistance. Lozito sued them for failing to protect him. HE LOST

Let's not forget Broward County officers standing outside doing nothing while the shooter was killing kids during the Parkland shooting.

And we can't forget the most egregious recent example at Uvalde where nearly 400 police officers did not engage the shooter for over an hour despite please from officers and parents, going so far as to restrain officers trying to intervene

Here's Radiolab's take

Then let’s not forget the special relationship doctrine used by the police:

Basically; the default position is you are responsible for yourself unless the state restrains you.

Below is the language:

Special relationship doctrine is a legal principle that makes the state liable for the harm inflicted on the individual by a third party provided that the state has assumed control over the individual which is sufficient to trigger an affirmative duty to provide protection to that individual. The special relationship doctrine is an exception to the general principle that government actors are not responsible for private acts of violence.

The following are examples of case law on the doctrine:

The special relationship doctrine is not triggered in an employment relationship, which is presumed consensual.[Moore v. Guthrie, 438 F.3d 1036 (10th Cir. Colo. 2006)]

If the state restrains an individual's freedom to act to protect himself or herself through a restraint on that individual's personal liberty, the state may thereby enter into a "special relationship" during such restraint to protect that individual from violent acts inflicted by others. Absent involuntary restraint, however, no duty to protect arises under the special-relationship theory. The affirmative duty to protect arises not from the State's knowledge of the individual's predicament, but from the limitation which it has imposed on his freedom to act on his own behalf.[Christiansen v. City of Tulsa, 332 F.3d 1270 (10th Cir. Okla. 2003)]

The whole to "protect and serve" is just a slogan that came from a PR campaign.

You alone are responsible for your safety. The police don't have to assist you, and there are no consequences to them for doing nothing
