The US government does not keep a comprehensive record of people killed by law enforcement, often leaving families, politicians and advocates powerless to quantify and analyse the size of the issue at hand. The lack of data has been glaring amid the protests, riots and the national debate set in motion by the fatal police shooting of Michael Brown last summer in Ferguson, Missouri. We lack the ability right now to comprehensively track the number of incidents," the outgoing US attorney general Eric Holder said before stepping down earlier this year. "Fixing this is an idea that we should all be able to unite behind." The Guardian has begun an investigative project, The Counted, to record the deaths of people at the hands of US police. When informed of the comprehensive reporting project, which will also be crowdsourced, the families of those whose deaths led to international attention called The Counted a breakthrough. [Many] relatives, campaign groups, activists and authorities ... argue that a national standard of mandatory accounting is a prerequisite for an informed public discussion about the use of force by police. Erica Garner-Snipes, daughter of Eric Garner: "Giving this kind of data to the public is a big thing. Other incidents like murders and robberies are collected, so why not police-involved killings? With better records, we can look at what is happening and what might need to change."
