One of the UK's biggest police forces will Twitter every incident it deals with for the next 24 hours.
Peter Fahy, Chief Constable of Greater Manchester Police (GMP), wants the public, and politicians, to see what his officers deal with on a daily basis.
"Policing is often seen in very simple terms, with cops chasing robbers and locking them up," he said.
"However, the reality is that this accounts for only part of the work they have to deal with.
"A lot of what we do is dealing with social problems such as missing children, people with mental health problems and domestic abuse. Often these incidents can be incredibly complex and need a lot of time, resource and expertise.
"I am not saying that we shouldn't deal with these types of incidents, far from it, but what I am saying is that this work is not recognised in league tables and measurements - yet is a huge part of what we do."
The event comes as police face unprecedented budget cuts, with the Government's impending comprehensive spending review next week.
Mr Fahy added: "I think that it's time to start measuring performance in a different way.
"There needs to be more focus on how the public sector as a whole is working together to tackle society's issues and problems.
"We see time and again the same families, the same areas and the same individuals causing the same problems and these people are causing a considerable drain to the public purse."
