Let me tell you a common trick that police will use. They'll tell you, "We'll go easy on you if you help us solve this crime and basically admit what you did. We'll talk to the district attorney and make sure that you get probation. We'll put in a good word for you with the judge." Don't fall for that. That's a lie. They don't have any authority to control what happens after they charge you with a crime. The person in authority is the district attorney. That's who can negotiate a settlement agreement with you or negotiate an outcome. Without the district attorney there, it's a baseless lie. When a police officer offers to help you, it's because he doesn't have enough proof to convict you. He wants you to tell what happened, and so he's going to trick you into making you think that he's in a position to help you. Don't fall for that.
