The usual reason is that there is something inthe film too close to a major real event so they think the film would be insensitive. But that film would always be insensitve to many - it's the whole point of it - how many odd ways can someone be bumped off.
What gets me more is when previous programs overrun, usually due to some sporting event, youve set your videa, and thus get a load of rubbish at the start and miss the ending
