Stop and search remains a hugely important police power for protecting Londoners, tackling crime and keeping our streets safe. It is an invaluable tool - especially in relation to knife crime; resulting in over 3,500 arrests for weapon possession and for taking several thousand weapons off the streets of London each year.

Stop and search must be used in a fair and effective way that supports public confidence and is independently scrutinised. Over the past few years we have changed the way we use stop and search, it is now used far less and is much more effective, complaints have reduced by 60 per cent. There are no individual numeric stop and search targets set for officers.

We do not underestimate the impact stop and search has on communities and individuals. We know that to maintain public confidence in its use, the power must be used in a fair and effective manner.

The primary purpose of stop and search is to enable officers to either allay or confirm their suspicions about an individual without having to arrest them. Effectiveness must therefore reflect where suspicion has been allayed and an unnecessary arrest, which is more intrusive, has been avoided; or where suspicion has been confirmed and the object is found or a relevant crime is detected. Presently 32 per cent, almost one in three of all searches, result in the officer's suspicion being confirmed and an illegal object found or a relevant crime detected. Our arrest rate is now 20%, up from 8 per cent in 2011.

We recognise the increase in knife crime and continue to make a concerted effort with operations such as Teal and Sceptre to tackle this. The aims of these operations are to remove knives from circulation and target habitual knife carriers. This includes the use of intelligence led stop and search, where it is an appropriate tactic, in areas with high levels of knife crime and gang violence.

Controlled drugs are a concern of many local communities and are often linked to anti-social behaviour. The overall outcome rate from drug searches is currently 34% and one third of all our weapons arrests from stop and search come from drug searches.

There is disparity in the use of stop and search in relation to gender, age and race. The reasons for disparity are complex and include the use of the power to tackle gangs and specific crimes. All measures of proportionality are subjective depending on which population base is employed. No population base will ever accurately capture a street population or offender profile in a given area, at a given time. In 2016, 42 per cent of people who were stopped and searched were white, 40 per cent were black and 14 per cent Asian.

In a survey of 9,492 school children in London aged 11 to 18 years conducted by the Mayor’s Office for Policing and Crime in 2015, 58 per cent of them believed stop and search made them feel safer.

Body Worn Video has been rolled out across the Met and will help to reassure Londoners that their interactions with the police are recorded. The technology offers greater transparency for those in front of the camera as well as behind it. The cameras will allow the Met to demonstrate the professionalism of officers, gather evidence and demonstrate their professionalism in the face of many challenges involved in policing the Capital.

The Met believes a stop and search is most likely to be fair and effective when:

  • the search is justified, lawful and stands up to public scrutiny
  • the officer has genuine and objectively reasonable suspicion they will find a prohibited article or item for use in crime
  • the person understands why they have been searched and feels that they have been treated with respect
  • the search was necessary and was the most proportionate method the police officer could use to establish whether the person has such an item

The Commissioner supports the use of stop and search in a fair and effective way that enhances public confidence and is independently scrutinised.

We will continue to work with our communities and stakeholders to improve the quality of interactions and ensure that stop and search continues to protect Londoners.
