Why did they record the video?
I couldn't help but wonder why Ricky Verona and his gang recorded that video that was played in the beginning. For one thing, it was evidence that they were behind the murder. Why would they leave that?
Another thing about it: How did they know that he would have "about one hour" left to live?
If he really had 1 hour left, why did they leave the video so that he would use that hour to hunt them down, rather then let him wonder what had happened for that hour and then die?
It seems like a plot hole to me. At least it does not seem conceivable that a gang would do that, or what?
