The police are not here “to protect and serve” you. That was just a motto someone in the LAPD came up with in 1950s. It has no legal bearing.
The police do not exist for the purposes of public safety. The Supreme Court has ruled they don’t have a duty to protect you from harm. They exist to protect property rights. Crime prevention is not their mission, nor do they solve crimes, with rare exceptions.
They are not your friends. They are not on your side.
