The use of stops and searches has fallen both in London and across England and Wales, following policy changes a few years ago.
Stops and searches are more likely than ever to result in arrest.
Around 17% of searches resulted in arrests, with 12% resulting in another kind of action in England and Wales in 2016/17.
Black people remain much more likely to be stopped and searched than white people, and this gap has widened in the most recent year we have figures for.
The rules on stop and search have changed
Almost all stops and searches take place under section 1 of the Police and Criminal Evidence Act 1984 and laws associated with that. It’s used by police to search people for things like drugs, weapons and stolen property, provided the officer has a reasonable cause to suspect they will find something. The use of section 1 searches has been declining rapidly in the last few years.
Stops and searches can take place under different laws as well, but those have also been falling rapidly and have now fallen largely out of use. This is due to changes in policy since 2012 to increase ‘fair use’ of the powers by the Home Office and Metropolitan Police.
The government also started a new scheme in 2014 called ‘Best use of stop and search’ which aimed to increase transparency around how stops and searches happened and to make forces more effective at identifying appropriate cases for using the powers.
The use of stop and search has fallen
The use of stop and search in England and Wales peaked in 2008/09 when over 1.5 million were carried out. It has declined in every year since then. Since 2011/12—just before the police changes were brought in—stops and searches have fallen by two-thirds.
The latest figures put them at just over 300,000 in 2016/17.
London has seen the same pattern. Stops and searches peaked in 2008/09 at nearly 600,000 and fell to just under 140,000 in 2016/17.
Stops and searches are more likely than ever to result in an arrest
Only 9% of stops and searches resulted in an arrest at the peak of its use in 2008/9. That proportion has increased in the years since and was 17% by 2016/17.
While it's tempting to take the higher arrest rate as an indicator of success, Her Majesty’s Inspectorate of Constabulary and Fire & Rescue Services note that an arrest isn't necessarily a success, nor is a failure to uncover any wrongdoing necessarily a failure.
Offenders could, for instance, be arrested even if they're found to be empty of stolen or prohibited goods because they might react violently to officers or be wanted for another offence. On the flipside, failing to uncover wrongdoing could be regarded as a success if, without the stop and search powers in place, the person under suspicion would otherwise have been arrested unnecessarily.
A third of stops and searches uncover something relevant
These are called “positive outcome” searches—which refers to any case where action is taken against people who’ve been stopped and searched. This includes arrest cases but also covers other resolutions like warnings and Penalty Notices. All cases where there isn’t a positive outcome are called ‘No Further Actions’.
Across England and Wales 29% of stops and searches had a positive outcome in 2016/17.
This figure could be higher in reality because some No Further Action cases do involve detentions under the Mental Health Act or informal advice being given when an officer has found something untoward.
The figures are similar for the Metropolitan Police in London, where in 2017/18 59% of stop and searches resulting in a “positive outcome” were related to drugs offences and 9% were for “weapons, points and blades”.
Outside the Metropolitan Police, police officers find what they’re searching for in one out of five cases
Police forces have to report whether the outcome was linked to the reason for the search.
For example, when someone is stopped for a drug search and given a cannabis warning the outcome is linked. If no drugs are found but they’re arrested for carrying a weapon the outcome isn’t linked. If nothing is found and no action is taken that also isn’t counted as linked.
So in England and Wales, officers found what they were searching for in around one in five searches. The reason for the search makes a big difference, with searches for drugs being more successful than stops for weapon searches or going equipped.
They also find that whether someone is white or not makes little difference—the rate is still about 20%.
Again, these cover ‘positive outcomes’ of stops and searches, but they’re different to the figures mentioned in the previous section because they only include cases where the officer found what they were searching for in the first place.
Black people are still more likely to be stopped and searched
The majority of the population is white and the majority of stops and searches involve white people. Per person, black people are more likely to be stopped and searched.
Black people are about eight times as likely to be stopped and searched as white people. Four in every 1,000 white people was stopped and searched in 2016/17, compared to 29 in every 1,000 black people.
The difference in rates between white and black people has grown since last year. Stops and searches have fallen in the last year overall but those involving white people have fallen faster than those involving black people.
Black people are more likely to be arrested following a stop and search. 22% of stops and searches on black people resulted in an arrest in 2016/17, compared to 16% of those conducted on white people.
In 2016/17 police were slightly more likely to find what they were looking for when searching BME people (23%) than when searching white people (21%).
We have more figures just for the Metropolitan Police in London covering April 2017 to March 2018.
Black people were four times as likely to be stopped and searched in London as white people—they were stopped 43 times per 1,000 people compared to 10 times for white people.
People of all ethnicities are more likely to be stopped and searched in London than elsewhere.
Positive outcome rates are similar whatever people’s ethnicity is. Around 30% of searches result in some action being taken.
