Id rather use the am i being detained or am I free to go and if detained enact your 5th amendment until suggested by council and 4th unless provided a warrant. If at your private property tell them to leave unless provided a warrant, and if provided a warrant enact your 5th and call a lawyer asap. If arrested when you go to first appearance plead not guilty.My go too answer when confronted by alphabet boys is " I sold it at a gunshow "
