Well done you! People's general mentality of 'he's probably a junkie' and 'someone else will deal with it' lead to shit like that person who was stabbed in NYC a while ago and bled to death on the pavement of a crowded street while everyone stepped over him.

Shit like that makes me sick. I've had to call the police or the ambulance for my alcoholic neighbor a lot of times, and yes, it's annoying to have to stay awake and give them a statement, but I don't really think there's any other choice, you know?
