If the police are talking to you, it’s because they suspect you have committed a crime. If they have detained you, it’s because they already have enough evidence to arrest you and they want to see if you will admit it and thus, give them an even stronger case against you.

If they have evidence to arrest you for a crime, they will. If they don’t, they won’t. It’s as simple as that. Talking to them or not talking to them won’t make a difference! No one has ever “talked his way out of” an arrest. If the police have enough evidence to arrest, they will.

Talking to the police cannot help you. It cannot prevent you from getting arrested. It can only hurt.

If you confess to the police, you get nothing in return. Zero. In fact, you probably get a harsher prosecution because the state’s case is now airtight, now that you have confessed.

If you want to rat on yourself, remember this: There is plenty of time to confess and admit guilt at a later stage of the proceedings. What’s the rush? Get a lawyer first. Let the lawyer set up a deal whereby you get something in exchange for accepting responsibility for the offense. A better plea bargain, or maybe even immunity.

Number One thing to remember: The police do not have authority to make deals, grant immunity, or negotiate plea agreements. The only entity with that authority is the District Attorney in state court and the U.S. Attorney in federal court. Despite their claim that they are trying to help you, the only help police are providing when they take your statement is giving you rope with which to hang yourself.
