Dante M. Sea, 24, was arrested and charged with aggravated battery Tuesday after he hit 60-year-old Eddie Thomas and broke Thomas' jaw, police said.
Thomas was staying in a shed in back of a military surplus store and Sea was sleeping in a tent on the same property, located in "Romneyville."
Sea took a piece of cardboard from Thomas' shed and that prompted the fight, police said. Sea was being held at the county jail. It was not immediately clear if he had an attorney.

Okay, it wasn't so epic, but I can dream! Never in my life have I been more in support and hopeful of Mutually Assured Destruction. Come on, WBC, kick their asses! Come on, #Occupy, kick their asses! Fairness and equality at last - everyone there is a loser.
