Carrying Tasers increases police use of force, study finds

Cambridge experiment with City of London police found that, while rarely deployed, just the presence of electroshock devices led to greater overall hostility in police-public interactions – an example of what researchers call the ‘weapons effect’.

A new study has found that London police officers visibly armed with electroshock ‘Taser’ weapons used force 48% more often, and were more likely to be assaulted, than those on unarmed shifts.

However, while use of force can include everything from restraint and handcuffing to CS spray, the Tasers themselves were only fired twice during the year-long study period.  

Criminologists from the University of Cambridge say the findings suggest that Tasers can trigger the ‘weapons effect’: a psychological phenomenon in which sight of a weapon increases aggressive behaviour.  

While the ‘weapons effect’ has been repeatedly demonstrated in simulated conditions over the last forty years, this is one of the largest studies to show it “in the field” and the first to reveal the effect in law enforcement.

Researchers say their findings, published today in the journal Criminal Justice and Behaviour, may well apply to policing situations in which other forms of weaponry – including the lethal variety – are involved.
