The Supreme Court ruled Monday that police cannot be sued for how they enforce restraining orders, ending a lawsuit by a Colorado woman who claimed police did not do enough to prevent her estranged husband from killing her three young daughters. . . Jessica Gonzales did not have a constitutional right to police enforcement of the court order against her husband, the court said in a 7-2 opinion. Hours later Simon Gonzales died in a gun fight with officers outside a police station. The bodies of the three girls, ages 10, 9 and 7, were in his truck.
