You must also be acutely aware that the cop has a gun and can invalidate all your rights with a single round of ammunition, and never be held to account for it.
The cops do not protect us. Anyone who believes they do is in for a rude shock. You have to assert your rights or else you don't have them. Even in a state of pusillanimity. These are your common law rights. Cops don't enforce laws. They enforce statutes which are corporate policy.
