You have already heard that "Court order prevents BBC from broadcasting film about riots." The BBC TV blog post below explains, that "The BBC will broadcast the programme at a later date."
BBC TV blog :: The riots across England in August 2011 should need no introduction.

Over five days trouble spread across the country with people looting, setting fire to property and attacking the police.
