The rates for the Netherlands and Germany appear to be calculated very differently. The German rate ("Aufklärungsquote") (percentage of solved crimes) includes cases that, according to the police, were sufficiently looked into. They don't care whether or not a case went before a judge or not. Fun fact: The rate can even surpass 100% since its sets solved crimes and reported crimes of one period in relation. That is, crimes solved from previous periods inflate the percentage. http://www.krimlex.de/artikel.php?BUCHSTABE=&KL_ID=23 http://www.krimlex.de/artikel.php?BUCHSTABE=&KL_ID=23 As for the Netherlands, their rate of solved crimes in indeed quite low (< 15 % in 2002). However, they also state that in many cases they don't even try to solve a crime because of a lack of priority(?) and missing initial suspicion (2/3 of all complaints to the police!) https://www.uni-muenster.de/NiederlandeNet/nl-wissen/politik/vertiefung/sicherheit/entwicklung.html https://www.uni-muenster.de/NiederlandeNet/nl-wissen/politik... --
