Knife bins and media campaigns to help reduce violence have little ‘positive impact’, research finds

Research suggests there is no evidence that money spent on knife bins and high-profile media campaigns to help prevent knife crime has “any real and lasting impact”.

Knife bins and high-profile media campaigns are two tactics commonly used across England and Wales to help prevent knife crime.

But new analysis of international research by the Home Office-funded charity the Youth Endowment Fund (YEF) suggests money is being spent on these initiatives without any evidence that they have any real and lasting impact.

Knife surrender schemes (also called weapon or knife amnesties) involve providing bins or collection points where people can drop off weapons with ‘no questions asked’.

When used for short periods by Gloucestershire Constabulary and Lincolnshire Police, in each county more than 300 weapons were handed in.

These schemes are often used alongside media campaigns to raise awareness of the risks and consequences of carrying knives or becoming involved in violence., said the YEF. These often involve advertising on TV, billboards or social media.

The YEF summarised research from the UK and abroad to see if these approaches work to reduce violent crime. In both cases, the charity found too few reliable evaluations to show any clear positive impact.

Two UK studies – in London and Glasgow – did suggest that knife surrender schemes may contribute to a small reduction in weapon-related offences.

“However, the effects did not last long and other factors, such as the police’s use of stop and search and increased presence on the streets, may also have contributed to the reduction,” said the YEF.

It said in the few UK evaluations available on the impact of media campaigns, there were instances where – against the intention of the campaign – young people became potentially more likely to carry a knife. When asked about campaign images of knives, young people actually said that it increased the perceived threat, which meant they felt a greater need to protect themselves.

Jon Yates, executive director of the YEF, said: “Do amnesty bins and hard-hitting media campaigns make our children safer? It looks pretty unclear that they do. Until we know more, we need to spend public money on the things that have the greatest chance of saving our children’s lives.”

Knife surrender schemes and media campaigns are the latest strands to be added to the YEF’s Toolkit. The free online resource ranks different approaches to reducing serious youth violence according to its impact, the quality of the available evidence and its cost. Approaches ranked as having a ‘high’ impact on preventing serious violence and are backed by strong evidence, include focused deterrence, cognitive behaviour therapy and social skills training.
