You may be found at fault because your life was not directly threatened causing your actions not to be justified. You could've gotten in a good heap of trouble just by beating the crap out those idiots. If they threatened your life verbally and pointed a gun at you then yes you have the right to defend yourself in an "equal" fashion. If they said to you "I'm gonna kick your @$$" and threw a punch at you then you are able to defend yourself in an "equal" fashion. I know that physical self defense thing sucks but I had to live by that rule for many years having licensed hands and had to take the 1st punch in the nose before "defending myself". However, NY laws may be a little different that ARK too.
