Questions raised about shooting 'link with Batman film'

Questions are being raised over any connection between the deadly shooting inside a packed Colorado cinema showing 'The Dark Knight Rises' and the film's plot and the Batman character.

In 'The Dark Knight Rises', a masked villain leads a murderous crew into a packed football stadium and wages an attack involving guns and explosives. It is one of the more haunting scenes in what was one of the most anticipated movies of the summer.
