Plot hole: A major plot device is Harry's fingerprints on a whisky glass at the murder scene. We see the glass being taken after he drinks from it at a bar. Why are there only his prints on it and not the bar staffs'? And why does no-one wonder why the victims prints aren't on it as well? If they think it is an attempt to frame him, why do they not even check if it matches any other glasses in the apartment or is an odd one out?

Continuity mistake: When Xavi racks the balls, their positions change dramatically when he takes off the triangle before the break. For example, the first ball is striped and then becomes a solid.
