Thug got aggressive because he thought George caught him casing a house he intended to rob later. What actually happened was George was just making sure that Thug got home safely because he knew that the neighborhood has had issues. Thug ran into a problem when the guy he was trying to kill had a gun to defend himself. Thug needs to lay 6 feet under so he could never attack another person.
See, I can make up stuff just like you.
