Perhaps if just one of these women had been armed?
Think the police will protect you?

Myth: Guns aren’t needed as self-protection.

About 83 percent of the population will be victims
of violent crime at some point in their lives, and
in any given year serious crime touches 25 percent
of all households. The odds are not likely to improve;
there is only one police officer on patrol for every
3,300 people. And the courts repeatedly have ruled
that government has at most a limited duty to protect
individual citizens from crime. An illustrative case
is Warren v. District of Columbia, in which three rape
victims sued the city under the following facts: Two
of the victims were upstairs when they heard the other
being attacked by men who had broken in downstairs. From
an upstairs telephone, the two roommates made several
calls to the police. Half an hour passed and their
roommate’s screams ceased; they assumed the police
must have arrived. In fact, however, their calls
had been lost in the shuffle while the roommate
was being beaten into silent acquiescence. When her
roommates went downstairs to see to her, as the court’s
opinion describes it, “For the next fourteen hours the
women were held captive, raped, robbed, beaten, forced
to commit sexual acts upon each other, and made to
submit to the sexual demands” of their attackers.

Having set out these facts, the District of Columbia’s
highest court nevertheless exonerated the District
and its police, noting that it is a fundamental principle
of American law that a government and its agents are
under no general duty to provide public services, such
as police protection, to any individual citizen.
