So you either have to lie or tell the truth.
The choice is yours but telling the truth will land you in jail and lying will weigh on your conscious because you did it just to keep out of jail.
“And anything you don’t tell the nice officers can not be used in your defense once you get hauled in front of the kangaroo.”
Defense against what exactly? They’re still going to have to justify a charge, and prove a case, against someone who was just sitting there not saying or doing anything.
