I live outside Liberty too. About 20 miles. I work just down the street from where this happened.
When this conversation came up at work, I mentioned that if it were me that discovered these people doing this, I Would be going to jail for assault. I would have grabbed that guy by the back of his head and shoved his face in the coals asking him how he likes it. Of course that was in the heat of the moment, dunno what I would do if 10 people were gathered around like it was said. Probably try it and get my ass kicked.
