He's only killing criminals. Many people believe that he is doing the right judgment. They just don't know certain things that only the police do. Which makes him a murderer in their eyes.
A lot of people don't exactly know how he kills either. Why just criminals? Why just people committing a certain dangerous crime? Any kind of crime at all now, sure the crime rate has gone down but he still continues on. Now they even starting to have a talk show all about him too.
[Slight chuckle] Sorry, I didn't mean to ramble off like that.
