Right. Go to Mr Pink's flashback scene. This seems to be a scene riddled with inconsistencies. Watch the part where Mr Pink is leaning against his "newly aquired" car and blasting away at the cops, who are shooting at him from the corner of the building.

As the camera zooms into Mr Pink while he is shooting, take a look at what the cops are doing. The one in the middle rolls over backwards (or is shot) and the other coppers with him turn around towards him.

Watch then as the camera shows the cops from behind as they shoot at Pink. They are suddenly all in a nice formation and shooting merrily. Nobody has rolled over, and nobody else has turned around.

I think that the shot of the cops shooting at pink was supposed to be shown before the shot of Pink shooting at them.
