IDK how is the shit in your countries/cities, but I'll be scared as f@#! man! How you know that criminal wasn't with a mate looking the situation hided there... from a distance, behind a car, I don't know... specially if it's a well know criminal as you say, now his mates could take revenge on your friend :s or even his friends, his family, his house... damnit! I don't know HOW THE HELL nobody is worried about that, that's the story of every day here, damnit nino!
Maybe I'm gettin' old or something xD but seruiosly, it's very possible what I'm talking about. I have a friend who almost died some years ago, due a similar situation, nowaday he is living in Uruguay, far far away from here. He fought with a friend vs. 2 criminals, with knifes, they both were cut in their faces, one lost an eye. The criminals were in the hospital when his house was labeled with spray paint at the next day when all happened.
Damn nino, take f@#!ing care, and remember... if you see someone strange, just press f12 and
