You might find yourself in any number of situations during the course of a typical (or not so typical) day where you encounter a Pennsylvania police officer. Perhaps you merely see an officer pulling someone over in a traffic stop. Then again, perhaps that someone is you. If that's the case, or if a cop shows up at your door while you're at home, it's critical that you know your rights and how to protect them.
It's always a bad idea to assume that nothing much will come of a police encounter. You might think that and then feel shocked when you wind up in handcuffs, riding to a county jail in the back of a patrol car. It can happen. Much depends on the details of a particular situation, as well as what you say and do while interacting with police. Knowing your rights ahead of time can prevent a lot of problems down the line, especially if you face criminal charges.
