"Turn your phone to silent and turn off vibrate": What is that about, so you don't give away your location? Only thing I can think of...And since it's opposite "HIDE".
Obey the police. PLEASE! ALWAYS OBEY THE POLICE! So RUN, HIDE, TELL. Don't fight, talk, build...Don't keep calm and carry on...Are we sure this is the message we want to send? To have people obey? Don't fight back? Don't try to disarm? Don't try to aid the injured? Na-ah. I ain't runnin', man. I ain't hidin'.
