After watching this film I had a question in my mind, wherever Tony Leung Ka-Fai gets shot or not but what I really want to know is why didn't we get to see or find out who was trying to kill Tony Leung Ka-Fai?
So is there anyone out there that have seen this movie and can tell me who it is?

A master piece, it has to be one of the best movie in 2000, even if I did get to find out whos the killer. Top marks 10/10
