Based on an investigation of all complaints against police officers in Skåne, Sweden in 2004 and comparative studies for 2005 and the first quarter of 2006 this study deals with who is making complaints, what the complaints are about, who gets reported and what happens with the complaint. In the discussion it is argued for a more proactive approach in dealing with human errors committed by police officers on duty. Most of the complaints (85%) are initiated by individuals, predominantly men with a mean age of 39 years. Based on the names of the complainants about 25% are supposed to have a nonNordic immigrant background which correspond to these immigrants share in Skåne as a whole. Based on data for a ten year period more than 60 percent are not convicted, or convicted of a crime that typically yields a fine, 35 percent of the complainants has been convicted of a prison verdict, almost 20 percent have more than one prison judgment. Just over half of the complaints from individuals contains criticism of bad attitude and treatment. The majority of these complaints includes complaints about excessive use of violence. Criticism of improper action incl. lack of action is included in almost 40 percent of the cases. 15 percent of the complaints are initiated by the police organization. Almost a third of these have been described as "Control notifications connected to special events" such as injuries during police interventions and "Goods, money, evidence etc. that is missing or destroyed". Just under 20 percent deal with "Wrong intervention including erroneous reporting." Of the identified policemen 9 percent are reported three or more times during the investigated period. 95 percent of these are men who work in external services, 70 percent are police inspectors, with an average of 16 years of service. The group accounts for a disproportionate share in terms of criticism for bad attitude and behaviour. Three-quarters of the group have one or more times been reported about excessive use of violence. In the data from 2004, preliminary investigation was completed in six of the cases (1%). More than half of the cases were terminated immediately without preliminary investigation. Most common causes of depreciation was "Not reason to believe offense is subject to public prosecution" followed by "Crime can not be proved".
