“This is a gruesome case, brought in 2005 by a Colorado woman named Jessica Gonzales. Gonzales had a restraining order against her ex-husband. But when he kidnapped her three children, the police ignored her requests for help. All three children were murdered. The Supreme Court ruled that the police had no obligation to enforce the restraining order.”
In other words, next time just pre-emptively murder your ex first instead of bothering with a useless restraining order
