En god og en dårlig nyhet: Om DNAs effekt på oppklaringsprosenten i vinningssaker
Abstract
The expansion of the Norwegian DNA database in 2008, the so called «DNA
reform», was founded on the belief that DNA increases the detection rate of
volume crime significantly. We have conducted a study of Norwegian police
registers to see what effects DNA actually has on detection rates in volume
crime. The good news is that there is little doubt that DNA affects the detection
rate. The overall detection rate for the criminal offenses we have studied in our
selected police districts in the selected period was 8 %. In cases with a DNA
profile the detection rate was 44 %. In cases with hits against the DNA identity
register the detection rate was 81%, and in cases with hits against the DNA
investigation register the detection rate was 62 %. However, the bad news is the
very low proportion of cases where police gather biological samples which
result in a DNA-profile and hits. This implies that no matter how high the
detection rate is in cases with DNA profile, it will not affect the overall
detection rate.
