The uncounted
A recent report estimated that there were 7,427 law enforcement homicides in the US during the eight years spanning 2003-2009 and 2011 — or an average of 928 per year. The number is more than twice as large as the closest previous official tally from the US government. Even the two best tallies — combined — left an estimated 2,103 homicides uncounted during those years.
