For more background on the decline in homicide clearance rates in the USA, here's a 2015 interview with Thomas Hargrove, the founder of murderdata.org: https://www.themarshallproject.org/2015/04/02/why-are-american-cops-so-bad-at-catching-killers https://www.themarshallproject.org/2015/04/02/why-are-americ... Hargrove claims that the overall decline in homicide clearance is a failure of local leadership: > It is the position of the Murder Accountability Project that declining homicide clearance rates are a failure of leadership by local police and by the politicians over them. When mayors and other elected officials make murder clearance a priority, as did the mayor of Philadelphia a few years ago, the clearance rate will improve significantly. If readers look at the “clearance rate” charts at our website, they will find hundreds of police departments that are doing a stellar job solving murders. > [...] we strongly believe that failure to solve murders are a failure of will by local leaders to make homicide clearance a priority in their communities. > That homicide clearance rates have plummeted despite the forensic revolution is one of the real mysteries in American law enforcement. The backlog of DNA testing has certainly slowed down the process in many cases. Lab testing may have forced a “pause” in murder investigations, which causes delays that can dramatically reduce the odds of a homicide being solved.
