Police have apologised over a controversial CCTV scheme which saw more than 200 surveillance cameras installed in two largely Muslim neighbourhoods in Birmingham.
West Midlands Police Chief Constable Chris Sims said he was "deeply sorry" that his force got the balance between counter-terrorism and excessive intrusion into people's lives "so wrong".
The cameras, some of which were hidden, sparked anger from residents in Sparkbrook and Washwood Heath in Birmingham, where they were predominantly installed. Civil liberties campaigners also expressed their anger at the scheme.
Mr Sims said there were "serious shortcomings" in the force's management of the Project Champion scheme.
"I am sorry that we got such an important issue so wrong and deeply sorry that it has had such a negative impact on our communities," he said.
"My real regret is that Project Champion has undermined the strong relationships that exist between West Midlands Police and our communities that have been built up over many years.
"When I became Chief Constable in 2009 I put strengthening the trust and confidence of communities at the heart of the changes we would make to policing. I am committed to continuing with these changes and rebuilding any trust we have lost."
He went on: "At the heart of the controversy surrounding Project Champion sits a dilemma faced by police on behalf of wider society, how to find a balance between on the one hand the duty to offer protection from serious harm and on the other the risk of excessive intrusion and the danger of stigmatising a whole community.
"I am convinced that when Project Champion was conceived in 2007 this dilemma was clearly understood. However, somewhere between conception and delivery the critical balance was lost."
Speaking to reporters at a press conference at West Midlands Police headquarters at Lloyd House, in Birmingham, he added: "There were serious shortcomings shown by the West Midlands Police management of this project.
"This allowed the specification to move beyond the point where it was proportionate to the community safety risks and counter terrorism threats that it aimed to address.
"At the same time, the vital consultation that should have accompanied the scheme proved wholly inadequate."
Mr Sims said he fully accepted the findings of an independent review, conducted by Thames Valley Police, of his force's handling of the scheme.
It found "little evidence of thought being given to compliance with the legal or regulatory framework" before the cameras were put up.
The review concluded that: "The consultation phase was too little too late, and the lack of transparency about the purpose of the project has resulted in significant community anger and loss of trust."
