Anti-police sentiment was a significant factor in the summer riots in cities across England, according to a major study on the causes of the unrest.
The study by London School of Economics and the Guardian newspaper involved interviews with 270 rioters.
Of those interviewed, 85% cited anger at policing practices as a key factor in why the violence happened.
Four consecutive nights of looting and arson in August left five people dead and more than 4,000 suspects arrested.
