And here is a quote from us:
“When a liberal acts up like this confront him and get into his/her face, Threaten to call the police and have them arrested for disturbing the peace or assault. If they continue to resist taunt them to hit you. When they do just clean the floor with them and give them an epic beating!”
Have an associate who can take a good video of the encounter with audio, or quickly recruit a bystandier who can:
don't raise your voice when talking to the disruptor;
make sure any physical contact is initiated by the disruptor;
don't use what you believe to be excessive force;
in a loud voice, tell the disruptor to stay down on the floor/ground until police arrive;
immediately email the video to the address on the business card of the responding LEO;
do not talk to the press or anyone you believe is associated with the disruptor, etc
