Quick notes: Why not talk to the police? You never want to confess to a crime, get caught lying to the police or look bad in front of a court. Talking to the police = If you're guilty of this crime, you might confess to it. If you’re not guilty of this crime, you might confess to it. If you’re not guitly of this crime, and do not confess, you might confess to another crime. If you’re not guilty of any crime and do not confess, you might lie. If you’re not guilty and do not confess and do not lie…
