At the scene...you have the right to remain silent....."USE IT!" ask for your lawyer at the station make your statement, have your lawyer do a picture and condition inventory of all your property , including firearms and ammunition, magazines and make sure that he gets the receipt signed by the property clerk and investigating officers.
Go thru reputable bail bondsman, if needed and hopefully it won't take a year or more for them to come to a conclusion and every time they want to talk to you, I want counsel present...
