Not all people are thugs. Sometimes a person is just put in a position where they have not choice but to defend themselves. Why is it that you always have to classify situations like this as thugs shooting thugs?
Wouldn't you defend yourself if someone came at you with violence and you thought you had to defend yourself for your life? And if you had to do so, would you call yourself a thug? Stop judging. Try to get all the facts before you speak.
