Yes you are all right. Don't ever tell the government anything without a lawyer present. If you have been arrested, they have enough evidence without you telling on yourself for you to go to jail.If you have been arrested and not charged, they are fishing for anything that is enough evidence to put you in jail.The VERY FIRST thing you need to state is your right to counsel. It is a constitutionally gauranteed right and cannot be overlooked unless you give them consent and waive this right.
Cops cannot make deals so do not think they will or can help you. It is entirely up to the prosecutor and judge.
