Well, it's not very common, last case I remember happened almost ten years ago or so. I guess the empathy toward own family is much stronger than empathy toward someone trying to harm it.
The fact that this kind of thing is viewed as maladjusted instead of perfectly fucking logical (if brutal) is emblematic of how stupid, fat, complacent and reliant upon arbitrary authority people have become. There's a goddamn good reason the vigilante is a popular subject of various forms of media. People say in public how horrible and dangerous vigilantism is and then they go home and watch a Batman movie, read a Punisher comic, hell they let their kids watch all kinds of stuff like this. Some of us fucking know better than to believe everything a person says with their public face.
