The leaving part is right. The po po's have fifteen minutes in order to produce a warrant, at the end of that time you are free to go. The officer will do all in his power to stop you, even violating your civil rights. He knows that you are a dumbass and will take a plea when you get your time in court. 95% of the people in prison agreed beforehand to go. If everyone fought their charges the court system would come to a stop. By the way, the K-9 is considered a person in the courts eyes, do battle with a dog and be charged with assault on a officer. Know your rights and be prepared for a legal battle and dont take a plea bargin.
