The Metropolitan Police has issued a statement in response to research carried out by the London School of Economics and The Guardian newspaper.
The following is a series of extracts.
"We continue to feel proud of the overwhelming bravery of our officers who were policing the disorder in London last year.
"Since that time we have reviewed and subsequently implemented significant changes to our public order strategy and tactics. A further 1750 public order officers have been trained, policing tactics to deal with large scale disorder have been changed, and we have implemented a mobilisation plan to deploy officers more effectively which we have already tested on occasions."
"The MPS continues to investigate crimes committed during that time, and our relentless pursuit of individuals involved has seen over 2,200 offenders brought to justice."

"The MPS has always acknowledged that there were lessons to be learnt from what were unprecedented scenes of violence last summer.
"We conducted a thorough review of the events of August 2011 in order to develop a detailed understanding of the MPS response to the significant public disorder in London.
"We took learning from a range of other reviews and enquiries and shared our findings, contributing as wholly as possible to improving the capability of the MPS and partners in dealing with public disorder and criminality. We made our report public in March this year."
Paul McKeever, Chairman of the Police Federation, has urged the government to take "urgent stock" of the results of a new study into the London riots.
He said that police would struggle to cope with further disorder if proposed austerity measures went ahead.

"This comprehensive analysis demonstrates what we have been telling the Government for two years now; that a 20% budget cut to policing will have a negative impact on public safety and that police numbers really do matter.
"Officers interviewed rightly identify and voice concern that, should the same circumstances occur again, the police service would struggle to cope and contain the situation with the loss of police officers numbers we are experiencing as a direct result of the cuts - over 5,000 last year alone."
Police Officers say they fear a repeat of last summer's riots, according to a new study.
The research, carried out by the London School of Economics and the Guardian, also suggests that police don't have the resources to cope with such disorder.
