Why did they even go to the mall?
Just saw this for the first time - maybe I just missed something, but was it ever explained why Chan, the witness, and the bad guys converged on the mall at the end? I'm glad they did, but I don't remember any explanation for it.
Edit: OK, I went back and I see now that apparently the bad guys' HQ was close to the mall. I'll leave this up in the interest of discussion, though.
What's the Spanish for drunken bum?
