In the past three years, more than 70 people are reported to have died in the USA and Canada after being struck by M26 or X26 tasers, with the numbers rising annually. In this report, Amnesty International calls US state, federal and local authorities to suspend all transfers and use of tasers and other electro-shock weapons pending a rigorous, independent inquiry into their use and effects. Where US law enforcement agencies refuse to suspend deployment of tasers, the organization is recommending that departments strictly limit their use to situations where the alternative would be use of deadly force, with strict guidelines, reporting and monitoring systems.
