I agree with the previous answer and you can talk your way into trouble , but it is a lawyer's job to talk your way out. If you try no good will come from it, obstruction of justice, false statements to law enforcement ,and perjury come to mind.
Do not speak with the police and it sounds as if they were trying to get an admission of guilt from you. If they had the admission or proof you would have been arrested already , there is no use in giving them the rope to hang you. Get a lawyer to help you.
Only If and until you and I sign an Agreement for Legal Services, I am not your attorney. These answers are provided for informational and/or novelty purposes
