The Hard Stop is a 2015 British documentary film, written and produced by George Amponsah and Dionne Walker, about the aftermath of the death of Mark Duggan, a young black man who lost his life at the hands of the Metropolitan Police in Tottenham, north London, in 2011 during a "hard stop" when officers "pulled out in front of Duggan's speeding cab, ready for confrontation". A peaceful protest about the event escalated into several days of rioting that spread across London and beyond, and for a time made news headlines around the world.
