Like a punch in the face

One of my co-coworkers was was walking back from an appointment this morning and someone, out of the fucking blue, punched him in the face.This seems to have been happening in a stretch of downtown Seattle for a month or two. One of these guys have been arrested 40 times for similar things in the past.What the hell?I can tell you if someone did that to me and I happened to be carrying... I can tell you that I would have no problem pulling the trigger on someone that attacked me like that. I know I would honestly fear for my life in that situation.Might just be me... but that's not something that I would sit on my conscience at all.
