The police have no duty to protect you; so says the Supreme Court:
"The Texas Legislature condemned the police response; and now heartbroken parents are left without a remedy. This is so because the U.S. Supreme Court has consistently ruled that the government and its agents have no duty to interfere with crimes that are in progress and no general duty to protect innocents. Under this line of cases, collectively called the DeShaney doctrine, the police can physically observe a bank robbery, a raepe or a murder, and lawfully do nothing.
Joshua DeShaney was a 4-year-old boy who had been repeatedly abused and irreparably brain damaged by his own father whose behavior was well-known to the local government. When the mother sued the government for failure to protect Joshua, the Supreme Court ruled that the government enjoys the common law privilege of allocating its resources with impunity. Stated differently, the government decides whom it will protect and whom it will let be. Not surprisingly, the DeShaney doctrine compels the government only to protect itself and those it has confined.
There is nothing in the Constitution that compels the DeShaney doctrine. It is just big government protecting itself. There are many selfless police throughout the country who would courageously interfere to stop violent crime because they have the ability to stop it and because it is always right to save innocent human life."
