I thought the Supreme Court ruled that cops don't have to put their lives on the line for another. If that is the case, I doubt this would hold up.

WASHINGTON, June 27 - The Supreme Court ruled on Monday that the police did not have a constitutional duty to protect a person from harm, even a woman who had obtained a court-issued protective order against a violent husband making an arrest mandatory for a violation.
The decision, with an opinion by Justice Antonin Scalia and dissents from Justices John Paul Stevens and Ruth Bader Ginsburg, overturned a ruling by a federal appeals court in Colorado. The appeals court had permitted a lawsuit to proceed against a Colorado town, Castle Rock, for the failure of the police to respond to a woman's pleas for help after her estranged husband violated a protective order by kidnapping their three young daughters, whom he eventually killed.
