STOP! Do not attempt to influence your government. Do not promote political or ideological causes. Do not allow yourself to act in any way that may be defined as terrorism. Do not attempt to distort the meaning of terrorism from that which the government that you may not influence prescribes. Do not talk with your companions. Do not examine your phone.

Please stay where you are, and await further instructions.
